Question: We request your explanation about the Islaamic ruling regarding the Qadiani group, and their self-procalimed “prophet” Ghulaam Ahmad al-Qadiani. We also request you send us some books which have researched this group since I am concerned in studying them?
Response: The prophethood was completed by our prophet Muhammad ﷺ so there is no prophet after him, for that which is confirmed in the Book and the Sunnah. So whoever claims prophethood after this, then he is a liar. And from amongst these [claimants] is Ghulaam Ahmad al-Qadiani. So his call of prophethood for himself is a lie, and that which the Qadianis (his followers) claim of his prophethood, then this claim is false.
And the judgement of the Council of Senior Scholars of Saudi Arabia was passed regarding the Qadianis, that they were a disbelieving sect because of their beliefs.
And with Allaah lies all success and may Allaah send prayers and salutations upon our Prophet ﷺ and his family and his companions.
