For your consideration, I will present to you some verses of Quran which Ahmadis believe refer to Ghulam Ahmad. But as I said before, the Jews deny the verses in Taurah which refer to Muhammad (sa), and the Muslims deny the verses in Quran which refer to Ghulam Ahmad.
I am not going to give you the Ahmadi translation of these verses, I am going to give you a word for word translation of these verses:
He it is Who raised among the unlettered ones a Messenger from among themselves, he recites upon them His Signs, and purifies them, and teaches them the Book and Wisdom, and before that they were in clear error; And others from them who have not yet joined them. And He is the Mighty, the Wise. [Quran 62:2-3]
In the above verses, Quran 62:2 says that Allah raised His messenger and this messenger purified the Unlettered (Arabs), and taught them the Book and Wisdom, while they were in clear error before.
But then Quran 62:3 says that this process will be repeated with others who have not yet joined the Arabs. Everybody knows that during the lifetime of Prophet Muhammad (sa), the message of Islam only extended meaningfully or sweepingly to the lands of Arabia, and even in Arabia there was not absolute dominance of Islam. Therefore, it seems that the process where Allah's messenger would purify these non-Arabs and teach them the Book and Wisdom would happen sometime after Muhammad's (sws) death. But who would do this task? Quran, as I said before, does not explicitly name or identify anybody, and this verse is somewhat mysterious.
Because this verse is not explicitly explained by Allah Himself in Quran, I think it's fair to present an explanation reported from Muhammad (sws) in Sahih Bukhari. Abu Hurairah (ra) asked him about who Quran 62:3 referred to, and Muhammad (sws) answered that if faith leaves the Earth, then a Persian man or Persian people would bring faith back to Earth.
Therefore, although 62:3 talks of Allah's messenger teaching the book to another people, clearly Prophet Muhammad (sws) regarded this verse as a prophecy about the distant future, when faith would leave the Earth, and he said that this prophecy would be fulfilled by a Persian or Persians.
Ghulam Ahmad (as) was of persian descent.
