Sayyiduna Abu Rafi’ (may Allah be pleased with him) says that I performed the ‘Isha prayer with Sayyiduna Abu Hurairah (may Allah be pleased with him). He recited Surah Inshiqaq and performed a prostration in it. I asked,“O Abu Hurairah! What kind of prostration is this?”He replied,“I performed this prostration following Abu al-Qasim (peace and blessings be upon him), so I will always continue to perform this prostration until I join him (peace and blessings be upon him).”
