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.”Tirmidhi and Abu Dawud transmitted it.
