as evidence that the lack of compatibility does not invalidate a marriage. Ahmad excused their marriages by stating that they were both Arabs, as they were from the tribe of Kalb, and that slavery had merely been an accidental state for them. According to this, this (41) is the ruling for every person of Arab origin.

Section: As for the people of innovation, Ahmad said regarding a man who marries his daughter to a Jahmi: "A separation is to be made between them." Likewise, if he marries her to a Waqifi, provided he is argumentative and a proselytizer. If he marries his sister to one of these Lafziyya (42) who has written down hadith, then this (43) is worse than a Jahmi, and a separation is to be made between them. He also said: "One should not marry his daughter to a Haruri who has apostatized from the religion, nor to a Rafidi, nor to a Qadari. However, if they are not proselytizing, there is no harm in it." He also stated: "Whoever does not place Ali fourth (44) among the Rightly Guided Caliphs, do not marry your women to them and do not speak to them." The Qadi said: "The marriage of a mere follower (muqallid) among them is valid, but the marriage of an activist (da'iya) among them is not valid."

Section: Compatibility is considered for the man but not for the woman. The Prophet, peace and blessings of Allah be upon him, has no equal, yet he married women from the Arab tribes, married Safiyya bint Huyayy, and took slave-women as concubines. He said: "Whoever has a slave-girl, educates her, gives her a good education, treats her kindly, then emancipates her and marries her, shall have a double reward." Agreed upon (45). This is because the child gains nobility through his father, not his mother, therefore it is not considered regarding the mother.
