Arabic hadith text
قَالَ سَمِعْتُ عِتْبَانَ بْنَ مَالِكٍ الأَنْصَارِيَّ، ثُمَّ أَحَدَ بَنِي سَالِمٍ قَالَ غَدَا عَلَىَّ رَسُولُ اللَّهِ صلى الله عليه وسلم فَقَالَ "لَنْ يُوَافِيَ عَبْدٌ يَوْمَ الْقِيَامَةِ يَقُولُ لاَ إِلَهَ إِلاَّ اللَّهُ. يَبْتَغِي بِهِ وَجْهَ اللَّهِ، إِلاَّ حَرَّمَ اللَّهُ عَلَيْهِ النَّارَ "
Translation
Narrated `Utban bin Malik Al-Ansari
who was one of the men of the tribe of Bani Salim: Allah's Messenger (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."
