What is the ruling on falling in love with a girl who studies with me in the same class, and proposing to marry her after the bachelor's degree, knowing that my family will not agree because I am the youngest of my siblings, and they have customs and traditions that require the elder to marry before the younger?

Love relationships between young men and women are not sanctioned by Islamic law and are a gateway to discord. If a man and a woman fall in love, marriage is the solution. Otherwise, they must turn away from this attachment and occupy themselves with what benefits them in their religious and worldly affairs. The questioner should take the initiative to marry the girl if possible; otherwise, he should remove this attachment from his heart and occupy himself with what benefits him, especially since he will be questioned on the Day of Resurrection about his life, his youth, his wealth, and his knowledge.
