How is inheritance calculated when there is one son, a full paternal uncle, and a paternal cousin?

If the heirs are limited to those mentioned, and the deceased left no other heir, then the entire estate belongs solely to the son by way of ta'sib (residuary heirship). The paternal uncle and the paternal cousin receive nothing, as they are completely excluded by the son. We must emphasize that matters of inheritance are serious and complex, and a mere fatwa is insufficient. Rather, the matter must be referred to the Sharia courts for review and investigation, as there may be other heirs, bequests, debts, or rights that the heirs are unaware of, and these take precedence over the heirs' right to the wealth. Therefore, the estate should not be divided without consulting the Sharia courts, if they exist.
