It is narrated from Hazrat Abdur Rahman bin Abi Laila (may Allah be pleased with him) on the authority of Ubayy bin Ka'b (may Allah be pleased with him) that during the blessed era of the Holy Prophet (peace and blessings be upon him), two men stated their lineage. One of them said to the other, "I am so-and-so, son of so-and-so, so who are you? May your mother not remain!" Upon hearing this, the Holy Prophet (peace and blessings be upon him) said that during the time of Hazrat Musa (peace be upon him), two men stated their lineage. One of them said to the other, "I am so-and-so, son of so-and-so," and he counted nine ancestors from among his forefathers and said, "So who are you? May your mother not remain!" The other replied, "I am so-and-so, son of so-and-so, son of Islam." Allah Almighty sent revelation to Hazrat Musa (peace be upon him) regarding both of them: "O you who ascribe yourself to nine men! All of them are in Hell, and you, the tenth, will be with them in Hell. And O you who ascribe your lineage to two men of Paradise! You will be the third with them in Paradise."
