According to the Holy Quran, Allah sent his prophets in all nations and places on earth, before the arrival of Last Messenger of Allah sall-Allahu alaihi wa-sallam.
Ancient India was also blessed with the arrival of prophets of Allah, though they are not mentioned in the Holy Qur’an, which gives a hint to their existence in following verses:
And there is a Guide for every people (13:7)
There is not a people to whom a warner has not been sent (35:24)
We sent not an apostle except (to teach) in the language of his (own) people, in order to make (things) clear to them. (14:4)
And, indeed We have sent Messengers before you; of some of them We have related to you their story and of some We have not related to you their story (40:78)
We do not know the names and locations of these prophets. However, Imam Rabbani Shaykh Ahmad Sirhindi, the great Mujaddid of the second millennium of Islam, saw the Noor (light) of such dignitaries and found a place where a few of those great prophets were buried.
It was a mound close to the town of Sirhind, in Indian Punjab. He would often go there and pray Nawafil. However he never pointed out the exact location of the graves, neither he told their names, though he clearly knew it from the knowledge bestowed on him from Allah.
According to one source, the place was occupied by Sikhs who recently started digging it up to build a Gurdwara. They felt a strong smell which was sweet but too strong. They called the Muslims, who, realizing it was the location of the noble graves, requested to return the land. It was returned by Sikhs and the Muslims then surrounded it with a compound, and built a mosque and madrasah with it.
Some legends say it holds nine prophets and four Sahaba. I have not tried to confirm this from reliable sources.
The exact location is: Baras Village, District Sirhind Sharif, Punjab, India.
Following are the pictures from that sacred place which holds the graves of some of the prophets of Allah sent to the ancient Indian people.
