عَنْ أَنَسِ بْنِ مَالِكٍ ـ رضى اللّٰه عنه ـ قَالَ قَالَ النَّبِيُّ صلّى اللّٰه عليه وسلّم: لاَ يَجِدُ أَحَدٌ حَلاَوَةَ الإِيمَانِ حَتَّى يُحِبَّ الْمَرْءَ، لاَ يُحِبُّهُ إِلاَّ اللّٰه، وَحَتَّى أَنْ يُقْذَفَ فِي النَّارِ أَحَبُّ إِلَيْهِ مِنْ أَنْ يَرْجِعَ إِلَى الْكُفْرِ، بَعْدَ إِذْ أَنْقَذَهُ اللّٰه، وَحَتَّى يَكُونَ اللّٰه وَرَسُولُهُ أَحَبَّ إِلَيْهِ مِمَّا سِوَاهُمَا.
Hazrat Anas bin Malikra narrated that the Prophetsa said: “No one will truly taste the sweetness of faith until he loves a person solely for the sake of Allah; and until being cast into the Fire is more beloved to him than returning to disbelief after Allah has delivered him from it; and until Allah and His Messenger are dearer to him than anything else.”
