COMPATIBILITY IS ONLY BASED UPON RELIGION AND PIETY
From the evil and reprehensible matters is that some who claim to be from the tribe of Haashim [i.e. claim to be a Sayyid; someone related to the Prophets (sallallaahu alayhi wa sallam) family] say that there is no kafaaah (marriage compatibility) between them and someone from outside of their own clan. So they do not get married outside of their clan, nor allow anyone from outside of their clan to marry them. This is a great error, a monstrous ignorance, oppression against the woman, and it is a legislation, which neither Allaah nor His Messenger (sallallaahu alayhi wa sallam) legislated or prescribed. Rather, Allaah - the Most High - said:
