What did the Messenger of Allah (saw) think about sleeping before or talking after the 'Isha' prayer, even up to the third part of the night?
 Sayyar b. Salama reported:                      I heard Abu Barza saying that the Messenger of Allah (may peace be upon him) did not mind some delay in the 'Isha' prayer even up to midnight and he did not like sleeping before (observing it) and talking after it. Shu'ba said: I again met him (Sayyar b. Salama) for the second time and he said: Even up to the third (part) of the night.
