Do not learn knowledge to boast before the scholars

It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Do not acquire knowledge in order to boast over the scholars with it, or to argue with the foolish with it, nor in order to secure a place in gatherings (to gain prominence) with it. Whoever does that, then for him is the Fire, the Fire."

It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) (like the previous hadith).
This is a chain that Yahya bin Ayyub al-Misri preserved by narrating it from Ibn Jurayj as connected, and Yahya is among the narrators whose narrations the two Shaykhs agreed upon. Although Abdullah bin Wahb narrated it as mursal, I remain upon my established principle that an addition made by a reliable narrator in chains and texts is to be accepted.

It is narrated from Ibn Jurayj that the Messenger of Allah (peace and blessings be upon him) said: "Do not learn knowledge in order to show off your superiority over the scholars, or to quarrel with the foolish, nor in order to talk with it in gatherings (to show your importance). Whoever does that, his abode is the Fire, the Fire."

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.
