Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings be upon him) said: "Whoever dies in such a state that he bears witness that there is no deity except Allah and I (Muhammad, peace be upon him) am the Messenger of Allah, and he departs (from this world) with a heart full of conviction, then Allah Almighty will forgive him."
