What is the ruling of Islamic law on dividing the profits of a deceased brother's business equally, given that the questioner manages the business and covers the expenses of the widow and orphan, and does the ruling differ between inherited goods and newly printed ones, and who bears the costs of the new goods?

The property of orphans must be preserved and not squandered or unjustly consumed. The paternal grandfather or guardian is primarily responsible for managing an orphan's property; otherwise, the judge assumes responsibility. Neither the mother nor the questioner has the right to dispose of an orphan's property without guardianship or the judge's permission. If the questioner is appointed over it, they must act in a way that benefits the property, and they may partake of it in a reasonable manner if they are in need. If the mother is a guardian or appointed by the judge, she may invest the orphan's property through legitimate means, and the questioner may contract with her under legitimate conditions. The goods left by the brother belong to his heirs, and the questioner should be a paid employee with a fixed wage if they undertake work related to the orphan's property.
