if one who is not free acquires something from his child’s wealth, whatever he acquires reverts to his master.
Is it a condition that he share his child’s religion? If we consider the general wording of the hadith, we would say that this is not a condition. Accordingly, a disbelieving father may take from the wealth of his Muslim child, and a Muslim father may take from the wealth of his disbelieving child. This is the apparent meaning of the hadith.
It has also been said that a disbelieving father is not to be permitted to take from the wealth of his Muslim child, because there is no bond between them and no mutual inheritance. Moreover, Allah Most High says: “Allah will never grant the disbelievers a way against the believers” [al-Nisāʾ 4:141]. Furthermore, if we were to permit the disbelieving father to take from the wealth of his Muslim child, this would humiliate the Muslim; perhaps the disbelieving father may even intend to humiliate his son by taking from his wealth.
In my view, there is no doubt that a disbelieving father has no right to take from the wealth of his Muslim child. As for a Muslim father taking from the wealth of his disbelieving child, here we may apply the general wording of the hadith and say that he may take, because the disbeliever’s remaining upon disbelief is itself unacceptable: he follows a religion that is not pleasing to Allah. Thus, placing the Muslim in authority over his wealth has a reasonable basis—especially if the son is among those at war with the Muslims, for if he is among them, there is no doubt that his wealth is lawful.
Thus, the statement, “he may,” refers to the father. We add the qualification “free,” and another qualification: “of the same religion,” according to the view of many scholars; or, according to the sounder view, that he not be a disbeliever taking from the wealth of a Muslim.
His statement, “and he may take and acquire”: the difference between the two is that taking is by way of use, whereas acquiring is by way of adding it to his own property. Thus, he may take his son’s car and use it to travel to Mecca, Riyadh, or Medina,
