Aisha once remarked, "It seems to me that your Lord hastens to satisfy your desire." Sahih Muslim vol.2 book 8 no.3453-3454 p.748-749.
Indeed. Mohammed was attracted to his step son's wife and told him:
"'Praise belongeth unto Allah who turneth the hearts of men as he willeth.'
"Zaid got the message
and arranged to divorce his wife. Muhammad knew quite well that nothing short of a new "revelation" could save his face from this detestable act, so he dissuaded Zaid from putting his wife away until the transaction could be sanctioned by a "revelation" from Allah:
"Behold! thou didst say to one who had received the grace of God and thy Favor: 'retain thou [in wedlock] thy wife, and fear God.' But thou didst fear in thy heart that which God was about to make manifest: thou didst fear the people, but it is more fitting that thou shouldest fear God. Then when Zaid had dissolved [his marriage] with her, with the necessary [formality], we joined her in marriage to thee: in order that in [the future] there may be no difficulty to the believers in [the matter of] marriage with the wives of their adopted sons, when the later have dissolved with the necessary [formality] [their marriage] with them. And God's command must be fulfilled." (Sura 33:37)" - from Islam Reviewed
This is one of the Koranic contradictions
since marriage to a step daughter
or son is considered incest.
