[2772] 216 - (...) It was narrated that Abū Salamah said: "We were talking about Lailat Al-Qadr, so I went to Abū Sa'eed Al-Khudrī [may Allāh be pleased with them], who was a friend of mine, and said: 'Let's go out to the palm trees.' So he came out, wearing a Khamīṣah, and I said to him: "Did you hear the Messenger of Allāh ﷺ mention Lailat Al-Qadr?" He said: "Yes; we observed I'tikāf with the Messenger of Allāh ﷺ during the middle ten days of Ramaḍān, and we came out on the morning of the twentieth. The Messenger of Allāh ﷺ addressed us and said: 'I was shown Lailat Al-Qadr but I forgot it' - or 'I was caused to forget it, so seek it in the last ten nights, on the odd-numbered nights. And I saw that I was prostrating in water and mud, so whoever was observing I'tikāf with the Messenger of Allāh ﷺ, let him go back.' So we went back and we did not see any clouds in the sky, then a cloud came and it rained, until the roof of the Masjid, which was made of palm branches, flowed with water. The Iqāmah was called for the prayer, and I saw the Messenger of Allāh ﷺ prostrating in water and mud, until I saw the traces of mud on his forehead."
