Tabari II:11 “Shem, the son of Noah was the father of the Arabs, the Persians, and the Greeks; Ham was the father of the Black Africans; and Japheth was the father of the Turks and of Gog and Magog who were cousins of the Turks. Noah prayed that the prophets and apostles would be descended from Shem and kings would be from Japheth. He prayed that the African’s color would change so that their descendants would be slaves to the Arabs and Turks.”
There you have it. Ham was the genetic link and "adam" if you will, of all black people. Allah is all wise and knowing. Let's double check, after all, several proofs remove all doubt in Islamic scripture.
Tabari II:21 “Ham [Africans] begat all those who are black and curly-haired, while Japheth [Turks] begat all those who are full-faced with small eyes, and Shem [Arabs] begat everyone who is handsome of face with beautiful hair. Noah prayed that the hair of Ham’s descendants would not grow beyond their ears, and that whenever his descendants met Shem’s, the latter would enslave them.”
There you have it, the 'fro" is entrenched forever in Islamic scripture, and ironically it's all Noah's falt that African women are cursed with nappy hair and have to constantly spend large amounts of money to chemically straighten it and iron it. Plus, African's will forever be slaves to Arabs.
Allah is all wise and knowing.
Bukhari:V4B52N137 “The Prophet said, ‘Let the negro slave of Dinar perish. And if he is pierced with a thorn, let him not find anyone to take it out for him.... If he [the black slave] asks for anything it shall not be granted, and if he needs intercession [to get into paradise], his intercession will be denied.’”
This last one is why Blacks shold never convert to Islam. Don't be fooled. You will NEVER go to Muhammad's brothel and get 72 virgins, pearly boys, not even a goat. They are tricking you. Allah is unforgiving.
