It is narrated from Sayyida Aisha (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: Whoever is done a favor, let him repay it; if he is unable to repay it, then let him mention it. Thus, whoever mentions it has expressed gratitude for it, and whoever displays a blessing which he does not possess is like a person who wears two garments of falsehood.
