I swear by whom my soul is in his hand, you will not enter Paradise until you believe, and you will not believe until you love each other. Do you want me to guide you to something which if you practice, you will love each other? Spread greeting with peace among of you." (Bukhari)
O My Generous Allah, will You grant our heart the love for salam?
When the dwellers of Paradise enter Paradise, an announcer will call: (you have a promise from Allah that) you will live therein and you will never die; you will stay healthy therein and you will never fall ill; you will stay young and you will never become old; you will be under a constant bliss and you will never feel miserable. (Muslim)
