As-Salaamu ‘alalikum wa Rahmatullahi wa Barakatuhum

That is great news—why do you “fear things will not be right in the future”?

Because you have not told me what makes you fear the future, I am going to respond to your question assuming that you fear that his Islam will not be sincere and that he only converted to marry you. Also, you may fear that your family may not trust his conversion. Also, his family may reject him if he converts….

If those are the reasons, then one way to figure out the answers to them is to take your time. After he takes his Shahada, wait—at least a few months—and see what happens before marrying him.  During that time, you can see if he was sincere. You can see what his family thinks—and does to him—they may disown him.

If, on the other hand, you have to marry him immediately after he converts because you and he can’t wait (you may commit zeena), then at least be aware of the risk that you are taking. You may end up suffering in your life with a person who is not a believer in Islam in his heart.

If he is a true believer in Islam in his heart, he will be able to deal with his family rejecting him—well, depending on how one defines the word “deal”. He may not “like” it if his family rejects him, but he will hold his ground if he is a true believer. But, if his conversion was only to marry you and you don’t marry him right away, then he may return to the religion of his family. It would be very important for you to find out the answer to this question before marrying him—beyond just what he tells you. if he takes his Shahada and deals with its fallout before you marry him, you will be able to be much more knowledgeable about what is “really” going on in his heart, InShaAllah.

Remember, kindness is not belief. The Prophet’s (Peace on him) uncle, Abu-Taalib, was all goodness to the Prophet (Peace on him) but to the end he was an unbeliever. Abu-Safyan, on the other hand, fought the Prophet (Peace on him) and became a Muslim in the end…. Go figure! Allah is the Guide!!!

All that to say, some people are “nice” out of pride—they are good because it makes them feel good about themselves. They are not conscious of or interested in doing good things to please Allah. The problem with that sort of goodness (for personal pride) is that it is not reliable the way “taqwa” is, i.e., God-consciousness. Taqwa is love for Allah and fear of Allah (that He Will Remove His Protection of you in this life and punish you in Hell in the next). Love of Allah (Who is Ar-Rahman, Ar-Raheem) gives us hope in His Mercy, that He will forgive our sins and save us from His Punishment—removing His Protection in this life and the Hell Fire in the Next). That “thinking” is the most reliable because nothing causes fear of sinning like the Hell Fire. And, nothing causes more devotion than love for Allah’s Rahma because that Love is The Best—the most imaginable! So, he may be a nice person now but without taqwa, that could change because the thing(s) behind his niceness are not the things that protect securely the reason for niceness—love of Allah and fear of His Punishment.

So, I strongly suggest you let him take his Shahada and then see what he does after that—when the storm (of his family’s reaction) hits… and May Allah Make it easy for you.
