Marrying relatives

Sayyiduna Abu Umamah (may Allah be pleased with him) reports this saying of the Prophet (peace and blessings be upon him): "The Hour will not be established until you once again become warmongers (or plunderers), and until a man goes to a Nabatean woman and marries her for the sake of a livelihood, and abandons his paternal cousin and does not look at her."
Al-Tabarani recorded it; its chain contains a narrator, Ja'far bin al-Zubayr, who is a kadhdhab (liar).

Sayyiduna Talhah (may Allah be pleased with him) narrates: I heard the Prophet (peace and blessings be upon him) say: "The one who marries among his own people is like one who grows grass in his own house."
Al-Tabarani recorded it; its chain contains a narrator, Ayyub bin Sulayman bin Hadhlam, and I did not find anyone mentioning him or his father; the rest of its narrators are thiqat (trustworthy).
