What do the learned muftis say in the following issue: A man named Nazar Muhammad has married twice, with his first wife having a son named Muhammad Khan, while his second wife, who was a widow, had a son named Abdul Rahim from her previous husband. Then, Nazar Muhammad had two sons named Wali Muhammad and Khan Muhammad, and now Abdul Rahim has passed away, and there are no heirs except his mother, Wali Muhammad and Khan Muhammad. Now, Nazar Muhammad's son from his first wife has claimed his share in Abdul Rahim's property. From an Islamic perspective, does Muhammad Khan have any right to Abdul Rahim's property or not?
According to the details given in the question, there is no relationship or kinship between Nazar Muhammad's son named Muhammad Khan from his first wife and the late Abdul Rahim, son of his second wife's former husband. Rather, both are strangers to each other. Therefore, Muhammad Khan has no share in the estate and inheritance of the late Abdul Rahim according to Sharia law. Therefore, Muhammad Khan must refrain from making unjust claims in the estate and property of the late Abdul Rahim.
