The Messenger of Allah سبحانه وتعالى, peace and blessings be upon him and his family, said: "Whoever swears to you by Allah سبحانه وتعالى regarding a right, then believe him, and whoever asks you in the name of Allah سبحانه وتعالى, then give him. The oath is for the claimant, and there is no claim for him without it."
