Sayyiduna Ubadah bin Samit (may Allah be pleased with him) narrates: I pledged allegiance to the Prophet (peace be upon him) along with some of my companions. The Prophet (peace be upon him) said:“I take your pledge on the condition that you will not associate anyone with Allah, you will not steal, you will not commit adultery, you will not kill your children, you will not falsely accuse anyone of adultery, you will not disobey in any good matter. Whoever among you fulfills his pledge, his reward is with Allah. And whoever commits any of these crimes and is punished for it, that will be a purification for him. And whoever Allah conceals (his sin), his matter is with Allah; if He wills, He will punish him (in the Hereafter), and if He wills, He will forgive him.”
