Abu Said al-Khudri (RA) reported that Allahs Messenger ﷺ spent in devotion (in itikaf) the middle ten nights of the month of Ramadan, and when twenty nights were over and it was the twenty-first night, he went back to his residence and those who were along with him also returned (to their respective residences). He spent one month in devotion. Then he addressed the people on the night he came back (to his residence) and commanded them as Allah desired (him to command) and then said: I used to devote myself (observe itikaf) during these ten (nights). Then I started devoting myself in the last ten (nights). And he who desires to observe itikaf along with me should spend the night) at his place of itikaf. And I saw this night (Lailat-ul-Qadr) but I forgot it (the exact night); so seek it in the last ten nights on odd numbers. I saw (the glimpses of that dream) that I was prostrating in water and mud. Abu Said al-Khudri said: It rained on the twenty-first night and the water dripped (from the roof) of the mosque at the place where the Messenger of Allah ﷺ observed prayer. I looked at him and as he completed the dawn prayer, (I found) his face was wet with mud and water.
