Allah has ninety-nine Names, i.e., one hundred minus one, and whoever believes in their meanings and acts accordingly, will enter Paradise; and Allah is witr (one) and loves 'the witr' (i.e., odd numbers).
لِلَّهِ تِسْعَةٌ وَتِسْعُونَ اسْمًا مِائَةٌ إِلاَّ وَاحِدًا لاَ يَحْفَظُهَا أَحَدٌ إِلاَّ دَخَلَ الْجَنَّةَ وَهْوَ وَتْرٌ يُحِبُّ الْوَتْرَ
Messenger of Allah 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)
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِنَّ لِلَّهِ تِسْعَةً وَتِسْعِينَ اسْمَا مِائَةً إِلاَّ وَاحِدًا مَنْ أَحْصَاهَا دَخَلَ الْجَنَّةَ
Messenger of Allah 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.
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِنَّ لِلَّهِ تِسْعَةً وَتِسْعِينَ اسْمًا مِائَةً إِلاَّ وَاحِدًا مَنْ أَحْصَاهَا دَخَلَ الْجَنَّةَ {أَحْصَيْنَاهُ} حَفِظْنَاهُ
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."
عَنِ النَّبِيِّ ﷺ قَالَ لِلَّهِ تِسْعَةٌ وَتِسْعُونَ اسْمًا مَنْ حَفِظَهَا دَخَلَ الْجَنَّةَ وَإِنَّ اللَّهَ وِتْرٌ يُحِبُّ الْوِتْرَ وَفِي رِوَايَةِ ابْنِ أَبِي عُمَرَ مَنْ أَحْصَاهَا
Verily, there are ninety-nine names for Allah, i. e. hundred excepting one. He who enumerates them would get into Paradise. And Hammam has made this addition on the authority of Abu Huraira who reported it from Allah's Apostle ﷺ that he said:" He is Odd (one) and loves odd number."
عَنِ النَّبِيِّ ﷺ قَالَ إِنَّ لِلَّهِ تِسْعَةً وَتِسْعِينَ اسْمًا مِائَةً إِلاَّ وَاحِدًا مَنْ أَحْصَاهَا دَخَلَ الْجَنَّةَ وَزَادَ هَمَّامٌ عَنْ أَبِي هُرَيْرَةَ عَنِ النَّبِيِّ ﷺ إِنَّهُ وِتْرٌ يُحِبُّ الْوِتْرَ
