Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates that the Prophet (peace and blessings be upon him) said: "Whenever the people of a household maintain the ties of kinship with one another, Allah Almighty causes their provision to flow to them, and they are under the protection of Allah."
Al-Tabarani recorded it; its chain contains a narrator, Ubaydullah bin al-Walid al-Wassafi, who is da'if (weak).
