Sahih al-Bukhari 7392

Arabic

حَدَّثَنَا أَبُو الْيَمَانِ، أَخْبَرَنَا شُعَيْبٌ، حَدَّثَنَا أَبُو الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ إِنَّ لِلَّهِ تِسْعَةً وَتِسْعِينَ اسْمًا مِائَةً إِلاَّ وَاحِدًا، مَنْ أَحْصَاهَا دَخَلَ الْجَنَّةَ ‏"‏‏.‏ ‏{‏أَحْصَيْنَاهُ‏}‏ حَفِظْنَاهُ‏.‏

English translation

Narrated Abu Huraira:Allah's Messenger (ﷺ) said, "Allah has ninety-nine Names, one-hundred less one; and he who memorized them all by heart will enter Paradise." To count something means to know it by heart
