QUALITIES OF THE SWEETNESS OF FAITH H 376 "When someone has these three qualities they taste the sweetness of faith; the love of Allah and His Messenger, praise and peace be upon him, above all others, loving someone just for the Sake of Allah, and abhorrence of ever reverting to disbelief after Allah rescued him from it in the same way that he would hate to be thrown into the Fire." R 376 Bukhari and Muslim with a chain up to Anas who related that the Prophet, praise and peace be upon him, said this.
375- وعن أنسٍ رضي الله عنه ، عن النَّبيّ صلى الله عليه وآله وسلم ، قَالَ : "ثَلاثٌ مَنْ كُنَّ فِيهِ وَجَدَ بِهِنَّ حَلاوَةَ الإيمانِ : أنْ يَكُونَ اللهُ وَرَسُولُهُ أحَبَّ إِلَيْهِ مِمَّا سَوَاهُمَا ، وَأنْ يُحِبّ المَرْءَ لاَ يُحِبُّهُ إلاَّ للهِ ، وَأَنْ يَكْرَهَ أنْ يَعُودَ في الكُفْرِ بَعْدَ أنْ أنْقَذَهُ الله مِنْهُ ، كَمَا يَكْرَهُ أنْ يُقْذَفَ في النَّارِ" مُتَّفَقٌ عَلَيهِ .
