Kathir bin Murrah says: Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) said during his illness of death: I heard a hadith from the Messenger of Allah (peace and blessings be upon him), I kept it hidden from you, now I am narrating it. The Prophet (peace and blessings be upon him) said: Whoever's last words are "La ilaha illallah" (There is no god but Allah), Paradise will become obligatory for him.
