Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) was having Surah al-Najm written down in his presence. When he reached the place of prostration, he prostrated, we prostrated along with him, and the inkpot and the pen also prostrated.
Al-Bazzar recorded it, and its narrators are thiqat (trustworthy).
