حدثنا عبد الرزاق حدثنا معمر عن الزهري قال أخبرني أبو سلمة بن عبد الرحمن والأغر صاحب أبي هريرة أن
عن رسول الله ﷺ قال ينزل ربنا تبارك وتعالى كل ليلة حين يبقى ثلث الليل الآخر إلى السماء الدنيا فيقول من يدعوني فأستجيب له من يستغفرني فأغفر له من يسألني فأعطيه
Its isnad is sahih. It has already appeared as 7582 from the narration of Ibrahim bin Saad from Zuhri, with this same isnad, with an addition at the end.In this isnad, in H, Abdul-Razzaq was omitted between Ahmad and Maamar. This is undoubtedly a printing error, which we have corrected from K and M.
