By the One in Whose Hand my soul is! You will not enter Paradise until you believe and you will not believe until you love one another other. Shall I tell you of something that, if you do it, you will love one another? Spread the greeting of peace among yourselves.[Muslim]

«وَالَّذِي نَفْسِي بِيَدِهِ، لاَ تَدْخُلُوا الجَنَّة حَتَّى تُؤْمِنُوا، وَلاَ تُؤْمِنُوا حَتَّى تَحَابُوا، أَوَلاَ أَدُلُّكُم عَلَى شَيءٍ إِذَا فَعَلْتُمُوهُ تَحَابَبْتُم؟ أَفْشُوا السَّلاَم بَينَكُم». [مسلم]
