Hisn al-Muslim 224
Fortress of the Muslim (Hisn al-Muslim)
Excellence of spreading the Islamic greeting
قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم: (لاَ تَدْخُلُوا الْجَنَّةَ حَتَّى تُؤْمِنُوا، وَلاَ تُؤْمِنُوا حَتَّى تَحَابُّوا، أَوَلاَ أَدُلُّكُم عَلَى شَيْءٍ إِذَا فَعَلْتُمُوهُ تَحَابَبْتُم، أَفْشُوا السَّلاَمَ بَيْنَكُمْ)
-- The Prophet (ﷺ) said: "You shall not enter Paradise until you believe, and you have not believed until you love one another. Shall I tell you of something you can do to make you love one another? Spread the greetings of Salam (peace) amongst yourselves (i.e. between each other). Reference: Muslim 1/74 and others.
