Is bringing the clothes of one's father, who is going to a wedding party where there is musical entertainment, considered cooperation in sin and transgression?

Assisting in sin and aggression has various forms, each with a different ruling. The Assembly of Muslim Jurists of America has divided it into four categories: 1. Direct and intentional: Such as someone giving another person alcohol with the intention of helping them drink it. 2. Direct and unintentional: Such as selling prohibited items that have no permissible use, if one does not intend to help others use them in a prohibited way. 3. Indirect and intentional: Such as someone giving another person a dirham to buy alcohol with it. 4. Indirect and unintentional: Such as someone selling something that can be used for both permissible and prohibited purposes without intending to assist users in the prohibited act, or someone giving another person money without intending to assist them in a prohibited act.

The Assembly has prohibited the first three types and permitted the fourth. Based on this, merely handing clothes to your father is not considered direct cooperation in sin, as long as you do not intend to assist him in wrongdoing, but rather intend to honor and obey him.
