the Messenger of Allah (saas) said: "Allah has ninety-nine Names, one hundred less one. Whoever counts them will enter Paradise." (Using translation from Ibn Mājah 3860)
وَقَالَ رَسُولُ اللهِ ﷺ لِلَّهِ تِسْعَةٌ وَتِسْعُونَ اسْمًا مِائَةٌإِلَّا وَاحِدًا مَنْ أَحْصَاهَا دَخَلَ الْجَنَّةَ إِنَّهُ وِتْرٌ يُحِبُّ الْوِتْرَ
