Narrated Al-Musaiyab
When the death of Abu Talib approached, Allah's Messenger (ﷺ) came to him and said, "Say: La ilaha illallah, a word with which I will be able to defend you before Allah."
Narrated Abu Huraira
Allah's Messenger (ﷺ) said, "(The following are) two words (sentences or utterances) that are very easy for the tongue to say, and very heavy in the balance (of reward), and most beloved to the Gracious Almighty (And they are): Subhan Allahi wa bi-hamdihi; Subhan Allahi-l-'Adhim,"
Narrated `Abdullah
Allah's Messenger (ﷺ) said a sentence and I said another. He said, "Whoever dies while he is setting up rivals along with Allah (i.e. worshipping others along with Allah) shall be admitted into the (Hell) Fire." And I said the other: "Whoever dies while he is not setting up rivals along with Allah (i.e. worshipping none except Allah) shall be admitted into Paradise."
