1Sahil B = ""Since the human body, which is the worker, has six sides, i.e. front, back, right, left, above and beneath, God, may He be exalted, sent six commanding messengers. They are: Adam, came to mankind from above; Noah, came to them from the left; Abraham, came to them from the back; Moses, came to them from beneath, opposite to Adam; Jesus, came to them from the right, opposite to Noah;, and Muhammad, may peace be upon him and his progeny, came to them from the front, opposite to Abraham. We say that, since man has six sides with respect to the body and it is the body which is the worker and since from each side of it an instructor came (to instruct man to work), then, according to intellectual judgment, it follows that no other instructor will come to mankind. Therefore, the decisive proof which we have shown according to intellectual judgment, establishes that after Muhammad, may peace be upon him and his progeny, there will not come any other Prophet in the future."Sayyidna Nāṣir-i Khusraw,(Wajh-i Din, Chapter VII, transl.
