Spreading the greetings of Salam (Peace)

The Messenger of Allah said:

‘You shall not enter paradise until you believe, and you shall not believe until you love one another. Shall I not inform you of something, if you were to act upon it, you will indeed achieve mutual love for one another? Spread the greeting amongst yourselves.

Aammar said: ‘Three characteristics, whoever combines them, has completed his faith: to be just, to spread greetings to all people and to spend charitably out of the little you have.

Aabdullah Ibn Aamr reported that a man asked the Prophet: ‘Which Islam is the best?’. He replied:

Feed the poor, and greet those whom you know as well as those whom you do not.
