(V.7:180) Allâh has one hundred minus one Names. (i.e. 99).
Narrated Abu Hurairah رضي الله عنه : Allâh has ninety-nine Names, i.e. one-hundred minus one; and whoever believes in their meanings and acts accordingly, will enter Paradise; and Allâh is Witr (One) and loves the ‘witr’. (Sahih Al-Bukhâri, Vol. 8, hadîth No.419).
