Muhammad (s.a.w) was born to parents who did not fornicate, but who instead were married. His forefathers were leaders among people, chiefs of tribes and sub-tribes. Each one of them inherited noble qualities from his forefathers.
The Prophet Muhammad His Lineage
In terms of his lineage, the Prophet Muhammad (saw) was the best, from the best - all the way back to his last forefather - Prophet Adam (as).
Muhammad (saw) was born to parents who did not fornicate, but who instead were married. His forefathers were leaders among people, chiefs of tribes and sub-tribes. Each one of them inherited noble qualities from his forefathers.
If you were to go back twenty years before the Prophet Muhammad's (saw) birth, you would not find a man who possessed the noble qualities that the Prophet Muhammad 's (saw) grandfather, Abdul Mutallib, possessed.
And, if you went a number of years further back, you would not find a man who was nobler and better than the Prophet Muhammad 's (saw) great-grandfather, Hashim.
The same can be said about all of the Prophet Muhammad's (saw) forefathers - Abd Manaf, Qusay, and every one of the Prophet Muhammad's (saw) forefathers between Qusay and Adam (as).
