Whoever offered Salat (prayer)in a silk Farruj (an outer garment opened at the back) and then took it off.

Narrated `Uqba bin 'Amir:

The Prophet (ﷺ) was given a silken Farruj [??] as a present. He wore it while praying. When he had finished his prayer, he took it off violently as if with a strong aversion to it and said, "It is not the dress of Allah-fearing pious people."
