It is also narrated from Sayyiduna Uthman bin Affan, may Allah be pleased with him, who says: I heard the Messenger of Allah, peace and blessings be upon him, say: "I know a word that whoever says it with sincerity of heart, the Fire will be made forbidden for him." Upon hearing this, Sayyiduna Umar, may Allah be pleased with him, said: "I will tell you what that word is; it is the word of sincerity by which Allah Almighty honored Muhammad, peace and blessings be upon him, and his companions. It is the word of piety which the Prophet of Allah, peace and blessings be upon him, presented to his uncle Abu Talib at the time of his death, and it is to bear witness to «لَا إِلَهَ إِلَّا اللَّهُ» ."
