Many Nabi and Rasul came in the world to call people to the path of Allah.
Our first Nabi is Hazrat Adam (A.).
And the last and greatest Nabi is Hazrat Muhammad (SM).
Hazrat Muhammad (SM) was born in Makkah.
He always spoke the truth and kept his promise. That's why everyone trusted him and used to called him “Al-Amin”. “Al-Amin” means very trustworthy.
The Holy Quran Majid was revealed upon Hazrat Muhammad (SM).
