As-Sirat is a bridge across the Hell.
قَالَ عَطَاءٌ وَأَبُو سَعِيدٍ الْخُدْرِيُّ جَالِسٌ مَعَ أَبِي هُرَيْرَةَ، لاَ يُغَيِّرُ عَلَيْهِ شَيْئًا مِنْ حَدِيثِهِ حَتَّى انْتَهَى إِلَى قَوْلِهِ " هَذَا لَكَ وَمِثْلُهُ مَعَهُ ". قَالَ أَبُو سَعِيدٍ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " هَذَا لَكَ وَعَشَرَةُ أَمْثَالِهِ ". قَالَ أَبُو هُرَيْرَةَ حَفِظْتُ " مِثْلُهُ مَعَهُ ".
Narrated 'Ata (while Abu Huraira was narrating ( see previous hadith )): Abu Sa`id was sitting in the company of Abu Huraira and he did not deny anything of his narration till he reached his saying: "All this and as much again therewith are for you." Then Abu Sa`id said, "I heard Allah's Messenger (ﷺ) saying, 'This is for you and ten times as much.' " Abu Huraira said, "In my memory it is 'as much again therewith.' "
