It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) used to observe i'tikaf in the middle ten days of Ramadan. Then one year he observed i'tikaf until the night of the twenty-first (21st of Ramadan), the morning of which he would come out of i'tikaf. The Messenger of Allah (peace and blessings be upon him) said: "Whoever has observed i'tikaf with me should also observe i'tikaf in the last ten days, for I was shown that (special) night, then I was made to forget it, and I saw myself prostrating in water and mud on its morning." Therefore, seek it in the last ten days and seek it in every odd night. Abu Sa'id (al-Khudri, may Allah be pleased with him) said: That night it rained, and the roof of the mosque was made of palm branches, which started to leak. Abu Sa'id (may Allah be pleased with him) said: My two eyes saw that on the morning of the twenty-first (21st), there were traces of water and mud on the forehead and nose of the Messenger of Allah (peace and blessings be upon him).

Lady Aisha, may Allah be pleased with her, the wife of the Prophet (peace be upon him), said: When the Messenger of Allah (peace be upon him) would observe i'tikaf, he would bring his head (out of the mosque) towards me and I would comb his hair, and he would only enter the house for human needs.

And with this chain (it is narrated from Sayyiduna Anas bin Malik, may Allah be pleased with him) that in Ramadan, the Messenger of Allah, peace and blessings be upon him, came to us and said: "Tonight (Laylat al-Qadr) was shown to me, until two men argued and it was taken away, so seek it in the ninth, seventh, and fifth (nights)."

And with this same chain (it is narrated from Sayyiduna Ibn Umar, may Allah be pleased with them both) that some people among the companions of the Messenger of Allah, peace and blessings be upon him, saw in their dreams that Laylat al-Qadr is in the last seven nights (of Ramadan). So the Messenger of Allah, peace and blessings be upon him, said: "I see that your dreams are in agreement with one another that Laylat al-Qadr is in the last seven nights, so whoever wants to seek it should seek it in the last seven nights."

And with this chain (it is narrated from Sayyiduna Ibn Umar, may Allah be pleased with them both) that the Messenger of Allah, peace and blessings be upon him, said: "Seek Laylat al-Qadr in the last seven nights."
