It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) recited Surah al-Najm in Makkah, and the people prostrated with him (peace and blessings be upon him), so much so that a man would lift something from the ground to his forehead and prostrate on it, and so much so that a man prostrated on top of another man.
