The ruling on refusing a righteous man in marriage because he is not from one's tribe

Question:
Is it permissible for a tribal girl to refuse a righteous suitor if he is not from her tribe?

Answer:
There is nothing wrong with this. If the guardian or the woman refuses a suitor who is not Arab, while she is Arab, for reasons they see—whether because it may lead to fitnah (trial, discord or temptation), or because her awliya (close friends of Allah) do not approve and they fear fitnah (trial, discord or temptation) among them—there is nothing wrong with this. But as our Lord (Glorified and Exalted is He) said: : [Surah al-Hujurat: 13], if they are pleased with him, there is no blame and nothing wrong. People are equal in status among themselves—if their religion is upright—whether they are Arabs, non-Arabs, or mawala (clients), there is nothing wrong with that.
The Prophet (peace and blessings be upon him) married Fatimah bint Qays—who was a Qurayshi—to Usamah ibn Zayd, who was a freed slave. He also married his father, Zayd, to Zaynab bint Jahsh al-Asadiyyah—she was the daughter of the Prophet’s (peace and blessings be upon him) paternal aunt, from the Asad tribe, and her mother was from the Hashim clan. There is no blame in that. Bilal also married the sister of 'Abd al-Rahman ibn 'Awf—she was from Quraysh—and Bilal was a mawla (client) of a slave from Abyssinia.
The conclusion is: there is nothing wrong with this if they agree upon it, and there is no blame in it. Allah the Exalted said: [Surah al-Hujurat: 13]. But if the guardian fears fitnah (trial, discord or temptation) between him and his relatives, there is no blame; he should seek for her a suitor whom her awliya (close friends of Allah) approve.
