قَوْلُهُ تَعَالَى: {فَاعْلَمْ أَنَّهُ لَا إِلَهَ إِلَّا اللهُ} [محمد: 19]
who was one of the men of the tribe of Bani Salim: Messenger of Allah ﷺ came to me and said, "If anybody comes on the Day of Resurrection who has said: La ilaha illal-lah, sincerely, with the intention to win Allah's Pleasure, Allah will make the Hell-Fire forbidden for him." (Using translation from Bukhārī 6423)
قَالَ رَسُولُ اللهِ ﷺ لَنْ يُوَافِيَ عَبْدٌ يَوْمَ الْقِيَامَةِ وَهُوَ يَقُولُ لَا إِلَهَ إِلَّا اللهُ يَبْتَغِي بِذَلِكَ وَجْهَ اللهِ ﷻ إِلَّا حَرَّمَ اللهُ عَلَيْهِ النَّارَ
