Contrary to the claim of some ignorant people of our era, who are unable to comprehend knowledge and say that it is not permissible to perform prostration upon reciting a verse of prostration during an obligatory prayer.

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).”
