Hazrat Abu Rafi’ narrates that I offered the ‘Isha prayer with Sayyiduna Abu Hurairah (may Allah be pleased with him), and he recited « إِذَا السَّمَاءُ انشَقَّتْ » [ سورة الإنشقاق ] and performed a prostration. I asked him, “What is this prostration?” He replied, “I performed prostration in this Surah behind Abu al-Qasim (peace and blessings be upon him).” San‘ani, narrating from his father, added at the end with these words: “I will continue to perform prostration in this Surah until I meet (the Prophet, peace and blessings be upon him) on the Day of Judgment.” Abu al-Ash‘ath says that « عن ابيه عن بكر بن عبدالله » he says: “I offered prayer behind Abu al-Qasim (peace and blessings be upon him), and he performed prostration in this Surah, so I will continue to perform prostration in this Surah until I meet Abu al-Qasim (peace and blessings be upon him).”
