It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Indeed, Allah Almighty (through the blessing of joining ties of kinship) prolongs the life of a people and increases their wealth, even though, since Allah created them, He has not looked at them (because of their disobedience) with anything but displeasure." The Companions said: "O Messenger of Allah! How can that be?" He (peace and blessings be upon him) said: "Because of their joining their ties of kinship." Imam al-Hakim says: Imran bin Abi Imran al-Ramli is one of the ascetics and devoted worshippers of the Muslims; if he has accurately preserved this hadith from Abu Khalid al-Ahmar, then it is gharib (singular) and sahih (authentic).

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that a man came to him and invoked a distant tie of kinship with him, so he said that the Messenger of Allah (peace and blessings be upon him) said: "Know your lineages (ancestry) so that you may join your ties of kinship, for a tie of kinship has no closeness when it is severed, however close it may be (in lineage), and it is not distant when it is joined, however distant it may be." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.
