Narrated Abu Huraira:
حَدَّثَنَا أَبُو الْيَمَانِ ، أَخْبَرَنَا شُعَيْبٌ ، حَدَّثَنَا أَبُو الزِّنَادِ ، عَنِ الأَعْرَجِ ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " إِنَّ لِلَّهِ تِسْعَةً وَتِسْعِينَ اسْمَا مِائَةً إِلاَّ وَاحِدًا مَنْ أَحْصَاهَا دَخَلَ الْجَنَّةَ " .
Allah's Messenger (ﷺ) said, "Allah has ninety-nine names, i.e. one-hundred minus one, and whoever knows them will go to Paradise." (Please see Hadith No. 419 Vol. 8)
