BUKHARI 6941:
from Muḥammad —
Messenger of Allah ﷺ said, "Whoever possesses the (following) three qualities will have the sweetness of faith (1): The one to whom Allah and His Apostle becomes dearer than anything else; (2) Who loves a person and he loves him only for Allah's Sake; (3) who hates to revert to atheism (disbelief) as he hates to be thrown into the Fire."
البخاري ٦٩٤١:
عن محمد —
قَالَ رَسُولُ اللَّهِ ﷺ ثَلاَثٌ مَنْ كُنَّ فِيهِ وَجَدَ حَلاَوَةَ الإِيمَانِ أَنْ يَكُونَ اللَّهُ وَرَسُولُهُ أَحَبَّ إِلَيْهِ مِمَّا سِوَاهُمَا وَأَنْ يُحِبَّ الْمَرْءَ لاَ يُحِبُّهُ إِلاَّ لِلَّهِ وَأَنْ يَكْرَهَ أَنْ يَعُودَ فِي الْكُفْرِ كَمَا يَكْرَهُ أَنْ يُقْذَفَ فِي النَّارِ
