An uncle's share of the inheritance

Q: Ahmad, Ibrahim and `Abdullah are three half brothers from the father. (Part No. 16; Page No. 537) Ahmad and `Abdullah died. Ahmad left behind one son named `Ali, while `Abdullah left behind several sons. Later, `Ali had a son who inherited from him when he died. After that, this only son of `Ali died as well. Ibrahim, the only one remaining of the three half brothers claimed to be the only rightful heir, excluding `Abdullah's sons from Ahmad's estate, his grandnephew. He based his claim on the fact that he is his father's paternal uncle from the father. Is this true?

A: If the case is as you mentioned, that the deceased has only male heirs, Ibrahim, who is `Ali's uncle who is the deceased's father, is worthier of receiving the inheritance than `Abdullah's sons because he is more closely related to the deceased, thus they are excluded. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
