ما هو الحديث الذي يحث على التعارف بين أي اثنين عند أول لقاء لهما؟

It is narrated in Sunan al-Tirmidhi that the Messenger of Allah, peace and blessings be upon him, said: "If a man fraternizes with another man, let him ask him for his name, his father's name, and from whom he is. For that is more conducive to affection." Al-Tirmidhi said: This is a gharib (strange) hadith; we do not know it except through this chain of narration, and we do not know of Yazid ibn Nu'amah hearing from the Prophet, peace and blessings be upon him. A similar hadith is narrated from Ibn 'Umar, but its chain of narration is not sound.
