Anas (Allah be pleased with him) reported:
When the 'Iddah of Zainab was over, Allah's Messenger (ﷺ) said to Zaid to make a mention to her about him. Zaid went on until he came to her and she was fermenting her flour. He (Zaid) said: As I saw her I felt in my heart an idea of her greatness so much so that I could not see towards her (simply for the fact) that Allah's Messenger (ﷺ) had made a mention of her. So I turned my back towards her. and I turned upon my heels, and said: Zainab, Allah's Messenger (ﷺ) has sent (me) with a message to you. She said: I do not do anything until I solicit the will of my Lord. So she stood at her place of worship and the (verse of) the Qur'an (pertaining to her marriage) were revealed, and Allah's Messenger (ﷺ) came to her without permission. He (the narrator) said: I saw that Allah's Messenger (ﷺ) served us bread and meat until it was broad day light and the people went away, but some persons who were busy in con- versation stayed on in the house after the meal. Allah's Messenger (ﷺ) also went out and I also followed him, and he began to visit the apartments of his wives greeting them (with the words): As-Salamu 'alaikum, and they would say: Allah's Messenger, how did you find your family (hadrat Zainab)? He (the narrator) stated: I do not know whether I had informed him that the people had gone out or he (the Holy Prophet) informed me (about that). He moved on until he entered the apartment, and I also went and wanted to enter (the apartment) along with him, but he threw a curtain between me and him, as (the verfes pertaining to seclusion) had been revealed, and people were instructed in what they had been instructed. Ibn Rafii had made this addition in his narration:" O you who believe, enter not the houses of the Prophet unless permission is given to you for a meal, not waiting for its cooking being finished..." to the words"... Allah forbears not from the truth."

Anas (Allah be pleased with him) reported:
I did not see Allah's Messenger (ﷺ) giving a wedding feast (on the marriage) of any one (of his wives) as he did in the case of (his marriage with) Zainab, for then he sacrificed a goat (on this occasion).

Anas b. Malik (Allah be pleased with him) reported:
Allah's Messenger (ﷺ) gave no better wedding feast than the one he did (on the occasion of his marriage with) Zainab. Thabit al-Bunani (one of the narrators) said: What did he serve in the wedding feast? He (Anas) said: He fed them bread and meat (so lavishly) that they (the guests) abandoned it (of their own accord after having taken them to their hearts' content).

Anas b. Malik (Allah be pleased with him) reported:
When Allah's Apostle (ﷺ) married Zainab bint jahsh, he invited people (to the wedding feast) and they ate food. They then sat there and entered into conversation. He (the Holy Prophet) made a stir as if he was preparing to stand up, but (the persons busy in talking) did not stand up. When he (the Holy Prophet) saw it, he stood up and when he did so, some other persons stood up. 'Asim and Abd al-A'la in their narrations made this addition: Three (persons) sat there, and Allah's Apostle (ﷺ) came there to enter (the apartment) but he found the people sitting there. Then they stood up and went away. He said: Then I came and informed Allah's Apostle (ﷺ) that they had gone away. He (the Holy Prophet) then came there until he entered (the apartment). I also went and was about to enter, when he hung a curtain between me and him (and it was on this occasion that) Allah, the Exalted and Majestic, revealed this verse:" O you who believe, enter not the houses of the Prophet unless permission is given to you for a meal, not waiting for its cooking being finished to the (words)" Surely this is serious in the sight of Allah" (xxxiii. 53).

Anas b. Malik (Allah be pleased with him) reported:
I was the best informed among the people pertaining to Hijab (veil and seclusion). Ubayy b. Ka'b used to ask me about it. Anas (Allah be pleased with him) thus narrated: The Messenger of Allah (ﷺ) got up in the morning as a bridegroom of Zainab bint jahsh (Allah be pleased witt her) as he had married her at Medina. He invited people to the wedding feast after the day had well risen. There sat Allah's Messenger (ﷺ) and there kept sitting along with him some persons after the people had stood up (for departure) ; then Allah's Messenger (ﷺ) stood up and walked on and I also walked along with him until he reached the door of the apartment of 'A'isha (Allah be pleased with her). He then thought that they (those who had been sitting there after meal) had gone away. So he returned and I also returned with him, but they were still sitting at their places. So he returned for the second time and I also returned until he reached the apartment of 'A'isha. He again returned and I also returned and they had (by that time) stood up, and he hung a curtain between me and him (at the door of the apartment of Hadrat Zainab, where he had to stay), and Allah revealed the verse pertaining to veil.

Anas b. Malik (Allah be pleased with him) reported:
Allah's Messenger (ﷺ) contracted marriage and he went to his wife. My mother Umm Sulaim prepared hais and placed it in an earthen vessel and said: Anas, take it to Allah's Messenger (ﷺ) and say: My mother has sent that to you and she offers greetings to you, and says that it is a humble gift for you on our behalf, Messenger of Allah. So I went along with it to Allah's Messenger (ﷺ) and said: My mother offers you salutations, and says that it is a humble gift for you on our behalf. He said: Place it here, and then said: Go and invite on my behalf so and so and anyone whom you meet, and he even named some persons. He (Anas) said: I invited whom he had named and whom I met. I (one of the narrators) said: I said to Anas: How many (persons) were there? He (Anas) said: They were about three hundred persons. Then Allah's Messenger (ﷺ) (said to me): Anas, bring that earthen vessel. They (the guests) then began to enter until the courtyard and the apartment were fully packed. Allah's Messenger (ﷺ) said: Make a circle of ten (guests), and every person should eat from that nearest to him. They began to eat, until they ate to their fill. A group went out (after eating the food), and another group came in until all of them had eaten. He (the Holy Prophet) said to me: Anas, lift it (the earthen vessel), so I lifted it, but I could not assess whether it had more (food) when I placed it (before Allah's Messenger) or when I lifted it (after the people had been served out of it). A group among them (the guests) began to talk in the house of Allah's Messenger (ﷺ) and the Messenger of Allah (ﷺ) was sitting and his wife had been sitting with her face turned towards the wall. It was troublesome for Allah's Messenger (ﷺ), so Allah's Messenger (ﷺ) went out and greeted his wives. He then returned. When they (the guests) saw that Allah's Messenger (ﷺ) had returned they thought that it (their overstay) was something troublesome for him. He (the narrator) said: They hastened towards the door and all of them went out. And there came Allah's Messenger (ﷺ) and he hung a curtain and went in, and I was sitting in his apartment and he did not stay but for a short while. He then came to me and these verses were revealed. Allah's Messenger (ﷺ) came out and recited them to the people:" O you who believe, enter not the houses of the Prophet unless permission is given to you for a meal, not waiting for its cooking being finished-but when you are invited, enter, and when you have taken food, disperse not seeking to listen to talk. Surely this gives the Prophet trouble", to the end of verse (xxxiii. 53). (Al-Ja'd said that Anas [b. Malik] stated: I am the first amongst the people to hear these verses), and henceforth the wives of the Apostle (ﷺ) began to observe seclusion (al-hijab).

Anas (Allah be pleased with him) reported:
When Allah's Apostle (ﷺ) contracted marriage with Zainab (Allah be pleased with bet), Umm Sulaim sent him hats in a vessel of stone as a gift. Anas stated that Allah's Messenger (ﷺ) said to him: Go and invite on my behalf all the Muslims whom you meet. So I invited on his behalf everyone whom I met. They entered (his house) and they ate and went out. And Allah's Messenger (ﷺ) had kept his hand on the food, and he invoked blessing on that, and said whatever Allah wished him to say, and none whom I met was left uninvited. They ate to their fill and went out, but a group among them remained there and was engaged in lengthy discussion. Allah's Apostle (ﷺ) felt shy of saying them anything. So he went out and left them in his house and Allah the Great and Majestic revealed this verse:" 0 you who believe, enter not the houses of the Prophet unless permission is given to you for a meal, not waiting for its cooking being finished." Qatada (instead of using the word Ghaira Nazirina) used the word Ghaira Mutahayyinina (i. e. not waiting for the time of the food). But when you are invited, enter..." up to this verse. This is purer for your hearts and their hearts.
