In the name of Allah, We praise Him, seek His help and ask for His forgiveness. Whoever Allah guides none can misguide, and whoever He allows to fall astray, none can guide them aright. We bear witness that there is none worthy of worship but Allah Alone, and we bear witness that Muhammad (saws) is His slave-servant and the seal of His Messengers.
Allah Says in the Holy Quran
(Lawful unto you in marriage) are (not only) chaste women who are believers, but chaste women among the People of the Book revealed before your time: when ye give them their due dowers and desire chastity, not lewdness nor secret intrigues. If anyone rejects faith fruitless is his work, and in the Hereafter he will be in the ranks of those who are losers.
Chapter 5 Surah Maidah verse 5 (part):
Allah Subhanah has permitted the believers to marry any chaste eligible women from amongst the believers, or any chaste eligible women from amongst the People of the Book (the Jews and the Christians). Provided all the conditions of a Shariah marriage are fulfilled, the marriage itself would be permissible, lawful and legal in the Sight of Shariah.
The Prophet (saws) said, “A woman is married for four things, i.e., her wealth, her family status, her beauty and her religion. So you should marry the religious woman (otherwise) you will be a loser.”
Sahih Al-Bukhari Hadith 7.27 Narrated by Abu Huraira
When choosing to marry from amongst the eligible women, the Messenger of Allah (saws) guided and recommended the believers to seek and strive to marry a righteous and religious woman. If one disobeys a direct command of Allah and His Messenger (saws), it is obvious that they would be ruined in this world and the Hereafter; but in our humble opinion, if one chooses to act against even an opinion or recommendation of Allah and His Messenger (saws), Allah is our witness brother, they would be utter losers.
