From Sahih Muslim (Hadith 1295):
Ibn 'Umar reported:The Messenger of Allah (ﷺ) while reciting the Qur'an recited its surah containing sajda, and he performed prostration and we also prostrated along with him (but we were so overcrowded) that some of us could not find a place for our forehead (when prostrating ourselves)
