I prayed the night prayer with Abu Hurairah, and he recited "When the sky has split" [Inshiqaq 84:1] and prostrated.I asked, "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 related it in adhan (766), and Muslim in mosques (110/578), both from Mutamir bin Sulayman Taymi, from his father, from Bakr, from Abu Rafi, who mentioned it. Bakr is Ibn Abdullah Muzani. And Abu Rafi is Nufay the goldsmith, known by his kunya.
