It is narrated from Hazrat Abu Barzah Aslami (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) used to delay the Isha prayer until a third of the night had passed, and he did not like sleeping before it or talking after it. And after offering the Fajr prayer, he would finish at a time when we could recognize the person sitting next to us, and he would recite between sixty to a hundred verses in it.
