It is narrated from Sayyiduna Ka'b bin Malik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever seeks knowledge in order to vaunt his superiority over the scholars, or to argue and dispute with the foolish, or to turn people's attention towards himself, he will go to the Fire." The two Shaykhs did not take any narration from Ishaq bin Yahya, but I have presented it as a shahid (supporting narration) in line with their condition, and Ishaq bin Yahya is among the nobles of Quraysh.
