It is narrated from Abu Salamah bin Abdur Rahman (may Allah have mercy on him) that he saw Sayyiduna Abu Hurairah (may Allah be pleased with him) performing the prostration of recitation upon reciting: ﴿إِذَاالسَّمَاءُانْشَقَّتْ﴾. Abu Salamah (may Allah have mercy on him) says: When Sayyiduna Abu Hurairah (may Allah be pleased with him) finished, I said: I have not seen people performing the prostration of recitation upon this surah; why do you do it? Sayyiduna Abu Hurairah (may Allah be pleased with him) replied: "If I had not seen the Messenger of Allah (ﷺ) performing the prostration in it, I would not do it."
