عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ لِلَّهِ عَزَّ وَجَلَّ تِسْعَةٌ وَتِسْعُونَ اسْمًا مِائَةٌ إِلَّا وَاحِدًا مَنْ أَحْصَاهَا كُلَّهَا دَخَلَ الْجَنَّةَ
Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Verily, Allah Almighty has ninety-nine names, that is, one less than a hundred; whoever memorizes all of them will enter Paradise.
