The names aren't mentioned in Quran but it is mentioned that Allah did send many Prophets and the numbers are mentioned in hadith. Some Prophets and messengers (pbut) have mentioned with their names also in Quran.
I'm not asking for the name but for the proof of another prophet(whatever his name) after the Prophet Muhammad(SAW) in Quran because as you claim that we can't be "complete muslims" without believing in Mirza Ghulam Ahmed so I'm asking for the proof of this claim.
I ll suggest to stick on fundamentals as the topic suggests. This will spread the current topic in hand. Or unless everyone wants to get into this particular discussion then I dont have any objection...( i am pretty sure objection does not count here..lolz)
