Hadrat Imâm-i Rabbânî says in the 67th letter of the second volume of his Maktûbât:

Prophets are people selected and sent by Allâhu ta'âlâ. They were sent to call their ummats to Allâhu ta'âlâ and pull them out of excessive, wrong ways into the way of salvation. They gave the good news of Paradise to those who accepted their invitation while intimidating with Hell torment those who disbelieved them. All the information which they brought from Allâhu ta'âlâ is right. There is no error in any of it. The last Prophet is Hadrat Muhammad 'sallallâhu alaihi wa sallam'. His dîn has transformed, abrogated all others. His book is the best of the heavenly books. His Sharî'at will remain valid until the end of the world. It will not be changed by anybody. Hadrat Isâ (Jesus) will descend from heaven, yet he will follow Hadrat Muhammad's Sharî'at; that is, he will join his Ummat.
