Sayyiduna Abu Sa'id (may Allah be pleased with him) said: I saw in a dream that I was reciting Sad [Surah Sad: 1]. When I reached the verse of prostration, everything fell into prostration, so much so that I saw even the inkpot, the pen and the tablet in prostration. In the morning I told the Messenger of Allah (peace and blessings be upon him) about it, and he (peace and blessings be upon him) gave the command to prostrate in it.
