Sayyiduna Abu Salamah (may Allah be pleased with him) said: I saw Sayyiduna Abu Hurairah (may Allah be pleased with him) prostrating in «إِذَا السَّمَاءُ انْشَقَّتْ» [سورة الانشقاق] , so it was said to him: "You prostrate in this Surah in which prostration was not done." He replied: "I saw the Messenger of Allah (peace and blessings be upon him) prostrating in it."

Sayyiduna Abu Salamah (may Allah be pleased with him) said: I saw Sayyiduna Abu Hurairah (may Allah be pleased with him) prostrating in «إِذَا السَّمَاءُ انْشَقَّتْ» [سورة الانشقاق 1/84] , so I asked: O Abu Hurairah! What is this, I see you prostrating in «إِذَا السَّمَاءُ انْشَقَّتْ» ? He replied: If I had not seen the Messenger of Allah (peace and blessings be upon him) prostrating in it, I would never have prostrated either.

It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him: The Noble Prophet, peace and blessings be upon him, performed prostration in «إِذَا السَّمَاءُ انْشَقَّتْ» .
