ذِكْرُ نَفْيِ الْإِيمَانِ عَمَّنْ لَا يَتَحَابُّ فِي اللَّهِ جَلَّ وَعَلَا
By him in whose hand my soul is, you will not enter Paradise until you believe, and you will not believe until you love one another: should I not guide you to something doing which you will love one another: spread out salutation among you. (Using translation from Abū Dāʾūd 5193)
قَالَ رَسُولُ اللَّهِ ﷺ « وَالَّذِي نَفْسِي بِيَدِهِ لَا تَدْخُلُوا الْجَنَّةَ حَتَّى تُؤْمِنُوا وَلَا تُؤْمِنُوا حَتَّى تَحَابُّوا أَلَا أَدُلُّكُمْ عَلَى أَمْرٍ إِذَا فَعَلْتُمُوهُ تَحَابَبْتُمْ؟ أَفْشُوا السَّلَامَ بَيْنَكُمْ»
