السَّلاَمُ عَلَيْكُمْ وَرَحْمَةُ اللهِ وَبَرَكَاتُهُ أحسن الله إليك Ustadh is it permissible for my brother to be with me when I show my face to the guy proposing, and not father because it’ll cause a lot of problems.

Maybe they can convince the father. Ibn Qudāmah said in al-Mughnī: “There is no disagreement among the people of knowledge regarding the permissibility of looking at her face, because it is not considered ‘awrah. It is the gathering place of beauty and the place that is normally looked at. It is not permissible to look at what does not normally appear. As for what usually appears besides the face, such as the hands, the feet, and the like—things a woman typically shows in her home—there are two narrations among the Hanbalis: The first: It is not permissible to look at it because it is ‘awrah, so looking at it is not allowed, just like what does not normally appear. The second—and this is the adopted position of the madhhab: The suitor may look at that. Ahmad said in the narration of Ḥanbal: ‘There is no harm in him looking at her and at what invites him to marry her, such as the hand, the body, and the like.’”
