Does the reward of one who spends on his family and sisters decrease in any way, even if he asks them to repay the costs of work visas after they have settled, despite the many financial pressures?

He who spends on his two sisters must be kind in his companionship with them and fear Allah concerning them, so that he may attain protection from the Fire and enter Paradise. This should be done while being careful not to remind them of his favors or harm them after showing kindness, lest his good deeds be invalidated. He should also advise his brother with wisdom and gentleness to share in the expenditure which is also obligatory upon him. It is permissible to take money for what was spent on work visas, provided that the work and travel adhere to Islamic regulations. However, it is not permissible to buy visas when there is no need or necessity.
