Silsilah as-Sahihah 351 — Knowledge of lineage helps in maintaining

It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: "Acquire enough knowledge of your lineage so that you may establish ties of kinship among yourselves, for maintaining ties of kinship creates love among relatives, brings blessings in wealth, and increases lifespan."
