Sunan an-Nasa'i, Volume 6, Book 47, Hadith 4990 (DarusSalam) ⓘ

It was narrated that Anas bin Malik said: "The messenger of Allah [SAW] said: 'There are three things, whoever attains them will find therein the sweetness of faith: When Allah [SWT], the Mighty and Sublime, and His Messenger [SAW] are dearer to him than all else; when he loves for the sake of Allah [SWT] and hates for the sake of Allah [SWT]; and when a huge fire be lit and he fall into it, than associate anything with Allah [SWT].'"

أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ أَنْبَأَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ طَلْقِ بْنِ حَبِيبٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ ثَلاَثٌ مَنْ كُنَّ فِيهِ وَجَدَ بِهِنَّ حَلاَوَةَ الإِيمَانِ وَطَعْمَهُ أَنْ يَكُونَ اللَّهُ عَزَّ وَجَلَّ وَرَسُولُهُ أَحَبَّ إِلَيْهِ مِمَّا سِوَاهُمَا وَأَنْ يُحِبَّ فِي اللَّهِ وَأَنْ يُبْغِضَ فِي اللَّهِ وَأَنْ تُوقَدَ نَارٌ عَظِيمَةٌ فَيَقَعُ فِيهَا أَحَبَّ إِلَيْهِ مِنْ أَنْ يُشْرِكَ بِاللَّهِ شَيْئًا ‏" ‏ ‏.‏
