Asalamu Alykum brother Sardar Miyan
Just to stay on the safe side, we don't know the number of messengers God has sent in the span of time. What we know is that the Quran narrates some of the stories of the messengers of the past and also there is also some messengers God did not mention. Just a little reminder.
4:164 And messengers We have mentioned unto thee before and messengers We have not mentioned unto thee; and Allah spake directly unto Moses;
40:78 We did aforetime send messengers before thee: of them there are some whose story We have related to thee, and some whose story We have not related to thee. It was not (possible) for any messenger to bring a sign except by the leave of Allah: but when the Command of Allah issued, the matter was decided in truth and justice, and there perished, there and then those who stood on Falsehoods.Salam
