حَدَّثَنَا عَمْرٌو النَّاقِدُ، وَزُهَيْرُ بْنُ حَرْبٍ، وَابْنُ أَبِي عُمَرَ، جَمِيعًا عَنْ سُفْيَانَ، - وَاللَّفْظُ لِعَمْرٍو - حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏ لِلَّهِ تِسْعَةٌ وَتِسْعُونَ اسْمًا مَنْ حَفِظَهَا دَخَلَ الْجَنَّةَ وَإِنَّ اللَّهَ وِتْرٌ يُحِبُّ الْوِتْرَ ‏"‏ ‏.‏ وَفِي رِوَايَةِ ابْنِ أَبِي عُمَرَ ‏"‏ مَنْ أَحْصَاهَا ‏"‏ ‏.‏

Abu Huraira reported Allah's Messenger (PBUH) as saying: There are ninety-nine names of Allah; he who commits them to memory would get into Paradise. Verily, Allah is Odd (He is one, and it is an odd number) and He loves odd number. And in the narration of Ibn 'Umar (the words are):" He who enumerated them." Translation Not Available
