Mukhtasar Bukhari (Abridged) 573 — Prostration in Surah Inshiqaq

Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that he recited Surah (Idha as-Sama'un Shaqqat) and performed a prostration in it. He was asked about this, so he said: If I had not seen the Noble Prophet (peace and blessings of Allah be upon him) performing the prostration, I would not have performed it.
