It is narrated from Sayyiduna Abu Kabshah al-Anmari (may Allah be pleased with him) that he said: "We went out with the Messenger of Allah (peace and blessings be upon him) on one of his military expeditions. We stopped at a halting place and came to him there. He (peace and blessings be upon him) raised both his hands and said: 'Faith and wisdom are here,' and he (peace and blessings be upon him) was pointing towards (the tribes of) Lakhm and Judham."
Urwah bin Ruwaym (may Allah have mercy on him) transmitted this hadith from Sayyiduna Abu Kabshah (may Allah be pleased with him), and no one other than Muhammad bin Muhajir (may Allah have mercy on him) narrated it.
