The Messenger of Allah ﷺ 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.’
AAammar 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.’
‘AAabdullah Ibn AAamr reported that a man asked the Prophet ﷺ: ‘Which Islam is the best?’. He ﷺ replied: Feed (the poor), and greet those whom you know as well as those whom you do not.’
