Usama b. Zaid reported God’s Messenger as saying, “If one is done a kindness and expresses to his benefactor a desire that God may give him a good reward, he has fully expressed his commendation.”
Anas said that when God’s Messenger came to Medina the Emigrants came to him and said, “Messenger of God, we have never seen people more liberal out of abundance or better in giving help when they have little than a people among whom we have settled. They have removed our trouble and shared with us their pleasant things so that we are afraid they will get the whole reward." He replied, ‘No, as long as you make supplication to God for them and express commendation of them*.”
* They have no reason to fear that the Ansar will get all the reward from God so long as due expression of thanks is made.
Jabir reported the Prophet as saying, “If anyone is given a gift and has the means he should make a return for it, but if he has not the means he should express commendation, for he who expresses commendation has given thanks, he who conceals a matter has been ungrateful, and he who decks himself with what he has not been given is like him who puts on the two garments of falsehood.”
