Sayyiduna Zaid bin Thabit (may Allah be pleased with him) says: We ate suhoor with the Messenger of Allah (peace and blessings of Allah be upon him), then he stood up for prayer. (Sayyiduna Anas (may Allah be pleased with him) says, I asked him) How much time was there between the adhan and suhoor? He said: As much time as it takes to recite fifty verses.
