I prayed the night prayer with Abu Hurairah, and he recited "When the sky is split asunder" [Inshiqaq 84:1], then he prostrated.I asked him, "What is this prostration?"He replied, "I prostrated at this verse behind Abu Qasim ﷺ, and I will continue to prostrate at it until I meet him."
صليت مع أبي هريرة العتمة، فقرأ: {إذا السماء أنشقت}. فسجد، فقلت: ما هذه؟ قال: سجدت بها خلف أبي القاسم ﷺ، فلا أزال أسجد بها حتى ألقاه.
Bukhari narrated it in "The Adhan" (766, 768), and in "Shortening the Prayer" (1078), and Muslim narrated it in "Mosques" (578/110), both of them through routes going back to Mutamir bin Sulayman Taymi, from his father, from Bakr bin Abdullah Muzani, from Abu Rafi (who was the goldsmith, one of the senior Tabiin), and he related it.In another version, "I prayed behind Abu Qasim ﷺ and he prostrated for it." Ibn Khuzayma reported this (561) through another route, from Abu Ashath Ahmad bin Miqdam, from Mutamir bin Sulayman, with the same wording.
