(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).
(V.7:187): Narrated ‘Abdullâh رضي الله عنه: Allâh’s Messenger صلى الله عليه وسلم said, "The keys of the unseen are five: Verily Allâh! With Him (Alone) is the knowledge of the Hour, He sends down the rain, and knows that which is in the wombs. No person knows what he will earn tomorrow, and no person knows in what land he will die. Verily, Allâh is All-Knower, All-Aware." (V.31:34). (Sahih Al-Bukhâri, Vol. 6, hadîth No. 151).
