Allah has one hundred Names less One

Narrated Abu Huraira:

Allah's Apostle 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.

حَدَّثَنَا أَبُو الْيَمَانِ، أَخْبَرَنَا شُعَيْبٌ، حَدَّثَنَا أَبُو الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ " إِنَّ لِلَّهِ تِسْعَةً وَتِسْعِينَ اسْمًا مِائَةً إِلاَّ وَاحِدًا، مَنْ أَحْصَاهَا دَخَلَ الْجَنَّةَ ". {أَحْصَيْنَاهُ} حَفِظْنَاهُ.
