Muwatta Imam Malik (Riwayat Ibn al-Qasim)

And it is narrated from (the same chain of narration from Sayyida Aisha, may Allah be pleased with her) that the Messenger of Allah, peace and blessings be upon him, prayed (the night) prayer (Tarawih) in the mosque, so (some) people prayed with him (behind him). Then on the following night, when he prayed, the people increased. Then on the third or fourth night, (many) people gathered, but the Messenger of Allah, peace and blessings be upon him, did not come out to them (to lead the prayer). When morning came, he, peace and blessings be upon him, said: "I saw what you did (last night), but I only did not come out to you because I feared that this (standing in prayer) might become obligatory upon you." This incident happened in Ramadan.

And with this chain of narration, it is narrated from Sayyiduna Anas (may Allah be pleased with him) that his grandmother, Sayyida Maleekah (may Allah be pleased with her), prepared food for the Messenger of Allah (peace and blessings be upon him) and invited him. The Messenger of Allah (peace and blessings be upon him) ate from it and then said: "Stand up! I will lead you in prayer." Anas (may Allah be pleased with him) said: I got up and went to my mat, which had become black due to lying for a long time, and I sprinkled water on it. Then the Messenger of Allah (peace and blessings be upon him) stood up, an orphan and I formed a row behind him, and the old woman stood behind us (in a separate row). The Messenger of Allah (peace and blessings be upon him) led us in two (nafl) units of prayer and then concluded with salam.
