Al-Kāfi|Volume 3|Book 4|Chapter 84
26ـ عَلِيُّ بْنُ مُحَمَّدٍ عَنْ سَهْلِ بْنِ زِيَادٍ عَنِ ابْنِ أَسْبَاطٍ عَنْ إِبْرَاهِيمَ بْنِ أَبِي الْبِلاَدِ قَالَ صَلَّيْتُ خَلْفَ الرِّضَا (عَلَيْهِ الْسَّلام) فِي الْمَسْجِدِ الْحَرَامِ صَلاَةَ اللَّيْلِ فَلَمَّا فَرَغَ جَعَلَ مَكَانَ الضَّجْعَةِ سَجْدَةً.
26. Ali ibn Muhammad has narrated from Sahl ibn Ziyad from ibn Asbat from Ibrahim ibn abu al-Balad who has said the following: “I performed my Salah (prayer), in Masjid al-Haram. Al-Rida’ ‘Alayhi al-Salam, led the Salah (prayer). It was Salah (prayer) of night. When he (the Imam) completed, he (the Imam) made his sleep (instead of sleeping after Salah (prayer)) into a Sajdah (prostration).”
