Sayyiduna Abu Rafi’ (may Allah be pleased with him) says: I offered the ‘Isha prayer with Sayyiduna Abu Hurairah (may Allah be pleased with him), and in it he recited“Idha as-samaa’un shaqqat”(the Surah), and performed a prostration in it. (After the prayer) I asked,“What kind of prostration did you perform?”He replied,“I performed this prostration behind the Messenger of Allah (peace and blessings be upon him), and I will continue to do it until I meet him.”(Meaning, I will continue to do it for the rest of my life.)
