Muslim Woman Marrying a Non-Muslim Man

Question:
Is it ok in Islam for a Muslim woman to marry a non-Muslim man? In what circumstances is it alright?
Answer:
All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad 
is His slave and Messenger.
According to the consensus of Muslim scholars it is forbidden to marry off a Muslim woman to a non-Muslim man. The suitability in the religion is the main condition since marriage provides the husband custodianship of his wife. Allah Says (what means):
• {And never will Allah grant to the disbelievers a way (to triumph) over the believers.} [Quran 4:141]
• {And do not marry polytheistic men [to your women] until they believe. And a believing slave is better than a polytheist, even though he might please you. Those invite [you] to the Fire, but Allah invites to Paradise and to forgiveness, by His permission.} [Quran 2:221]
If a Muslim woman marries a non-Muslim man, the husband and wife must separate, and she should not permit him to enjoy her since the marriage is not lawful.
For more benefit on the absolute prohibition of a Muslim woman marrying a non-Muslim man, please refer to Fataawa 90619, 87151, 274252, 124877, 84265, and 88406.
Allah knows best.
