Hadeeths about memorising 99 names of Allah:
Narrated by Abu Huraira: Allah's Apostle (may peace be
upon hime) said, Allah has ninety-nine Names, i.e., one hundred minus one, and whoever
memorise them, will enter Paradise.
[Sahih Al Bukhari (Book of Shroot)].
Narrated by Abu Huraira: Allah's Apostle (may peace be
upon hime) said, Allah has ninety-nine Names, i.e., one hundred minus one, and whoever
memorise them, will enter Paradise. Allah is Witr (one) and loves 'the Witr'
(i.e., odd numbers).
[Sahih Muslim (Book of Dhikr)].
