Sahih al-Bukhari, Hadith 6938 ⓘ
Narrated `Itban bin Malik: Once Allah's Messenger came to me in the morning, and a man among us said, "Where is Malik bin Ad- Dukhshun?" Another man from us replied, "He is a hypocrite who does not love Allah and His Apostle." The Prophet said, "Don't you think that he says: None has the right to be worshipped but Allah, only for Allah's sake?" They replied, "Yes" The Prophet said, "Nobody will meet Allah with that saying on the Day of Resurrection, but Allah will save him from the Fire."
حَدَّثَنَا عَبْدَانُ، أَخْبَرَنَا عَبْدُ اللَّهِ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، أَخْبَرَنِي مَحْمُودُ بْنُ الرَّبِيعِ، قَالَ سَمِعْتُ عِتْبَانَ بْنَ مَالِكٍ، يَقُولُ غَدَا عَلَىَّ رَسُولُ اللَّهِ صلى الله عليه وسلم فَقَالَ رَجُلٌ أَيْنَ مَالِكُ بْنُ الدُّخْشُنِ فَقَالَ رَجُلٌ مِنَّا ذَلِكَ مُنَافِقٌ لاَ يُحِبُّ اللَّهَ وَرَسُولَهُ. فَقَالَ النَّبِيُّ صلى الله عليه وسلم " أَلاَ تَقُولُوهُ يَقُولُ لاَ إِلَهَ إِلاَّ اللَّهُ يَبْتَغِي. بِذَلِكَ وَجْهَ اللَّهِ ". قَالَ بَلَى. قَالَ " فَإِنَّهُ لاَ يُوَافَى عَبْدٌ يَوْمَ الْقِيَامَةِ بِهِ إِلاَّ حَرَّمَ اللَّهُ عَلَيْهِ النَّارَ ".
