Narrated from Sayyiduna Anas (may Allah be pleased with him) that Zaid bin Thabit (may Allah be pleased with him) told me that the Companions (may Allah be pleased with them) ate suhoor with the Prophet (peace and blessings of Allah be upon him), and then stood up for prayer. So I asked, "How much time was there between the two?" Sayyiduna Zaid (may Allah be pleased with him) said, "The time it takes to recite fifty or sixty verses (of the Qur'an)."
