Musannaf Ibn Abi Shaybah 5582 — The hour hoped for on Friday

Sayyidah Aishah (may Allah be pleased with her) says: Friday is like the Day of Arafah; the doors of mercy are opened in it. In it there is an hour in which, whatever the servant asks of Allah Almighty, it is granted to him. Sayyidah Aishah (may Allah be pleased with her) was asked: Which hour is it? She said: When the muezzin calls the adhan for Fajr.
