"I'll be a monkey's uncle."

In the name of Allah the Beneficent, the Merciful

My first response to your question is, "no". But looking at your question again, you ask, "can the grafted one be grafted back" The answer to that question is yes, they can be grafted back into the Original man and it would take 600 years. However, "instead of losing time grafting him back", the decision has already been made to take him off the planet.

Some of the devils did make an attempt to graft themselves back into the Black nation after they were first made 6,000 years ago. The Honorable Elijah Muhammad writes in Message to the BlackMan - The Making of Devil, "They lost all knowledge of civilization. The Lord, God of Islam, taught me that some of them tried to graft themselves back into the black nation, but they had nothing to go by. A few were lucky enough to make a start, and got as far as what you call the gorilla. In fact, all of the monkey family are from this 2,000 year history of the white race in Europe."
