The Prophet ﷺ said, "People will pass over the bridge of Hell." He then mentioned the rest of the hadith, saying, "On either side of the bridge will be angels saying, 'O Allah, grant safety, grant safety.'"
عن النبي ﷺ أنه قال: يمر الناس على جسر جهنم. فذكر الحديث قال: بجنبتيه ملائكة يقولون: اللهم سلم سلم.
Ahmad (11201) and Abu Yaala (1253) both narrated it from Rawh, who said, Uthman bin Ghiyath narrated to us, Abu Nadra narrated to us, from Abu Saeed, and he related the hadith in full, which will come complete in its place. Ibn Khuzayma (7379) graded it sahih through this route.
