Sayyiduna Abu Hurayrah (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) said: "When any of you prays the two rak'ahs of Fajr, let him lie down on his right side."
(Note) Marwan bin al-Hakam (may Allah have mercy on him) said to him: Is it not enough for one of us to walk to the mosque, instead of lying down on his right side? In the narration of Ubaydullah: He (Abu Hurayrah) said: No. This reached Sayyiduna Ibn Umar (may Allah be pleased with them both), and he said: Abu Hurayrah (may Allah be pleased with him) has narrated a great deal on his own account. Sayyiduna Ibn Umar (may Allah be pleased with them both) was asked: Do you reject anything of what he says? He said: No, but he was bold and we were timid. When this reached Sayyiduna Abu Hurayrah (may Allah be pleased with him), he said: What is my fault if I memorised and they forgot?
