Narrated `Aisha: Allah's Messenger (sallallahu 'alaihi wa sallam) once delayed the `Isha' prayer and that was during the days when Islam still had not spread. The Prophet (sallallahu 'alaihi wa sallam) did not come out till `Umar informed him that the women and children had slept. Then he came out and said to the people of the mosque: "None amongst the dwellers of the earth has been waiting for it (`Isha prayer) except you."
