Arabic (Original)
حَدَّثَنَا إِسْمَاعِيلُ عَنْ هِشَامٍ وَيَزِيدُ يَعْنِي ابْنَ هَارُونَ قَالَ أَخْبَرَنَا هِشَامٌ عَنِ ابْنِ سِيرِينَ عَنْ أَبِي هُرَيْرَةَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لِلَّهِ عَزَّ وَجَلَّ تِسْعَةٌ وَتِسْعُونَ اسْمًا مِائَةٌ إِلَّا وَاحِدًا مَنْ أَحْصَاهَا كُلَّهَا دَخَلَ الْجَنَّةَ.
English Translation
Isma'il narrated to us, from Hisham, and Yazid - meaning Ibn Harun - said: Hisham informed us, from Ibn Sirin, from Abu Hurairah, who said: The Messenger of Allah (peace be upon him) said: "Allah, the Mighty and Sublime, has ninety-nine names - one hundred less one. Whoever memorizes them all will enter Paradise."
