Was Abd al-Rahman ibn Awf originally the guardian (wali) of Umm Hakim bint Qariz when he married her, or did Al-Bukhari and others consider him a guardian after Umm Hakim asked him to marry her to the most suitable person following multiple suitors?

The marriage of Abdur-Rahman ibn Awf to Umm Hakim is confirmed. Abdur-Rahman was from Banu Zuhra. Qariz ibn Khalid (Umm Hakim's father) was an ally of Banu Zuhra and is not mentioned among the Companions, which indicates that he did not embrace Islam or did not live to see the advent of Islam. The narration transmitted by Qariz to his son, found in An-Nasa'i, is not from Umm Hakim's father but from another Qariz, possibly Qariz ibn Shaybah. Abdur-Rahman had guardianship over Umm Hakim due to the alliance between his tribe and her father's tribe. Had Umm Hakim's father been alive at that time, he would have been mentioned in the matter.
