Question Summary:
I want to marry a man who is disabled and is unable to conceive children.

Question Detail:

I want to marry a disabled man (wheel chair bound) who cannot have a normal intercourse neither conceive children due to his illness. Apart from my obvious sympathy towards this male (he is an observing Muslim) I feel that I can enjoy the intimate life in a way that suites his disability and is satisfying for me as well. I think I can offer him a relationship that he will hardly be able to establish with another woman, at least in his culture where no family will give its daughter to a disabled man.
 I myself have no Muslim relatives. Is there any ruling on marrying such a person? Is there an example from Sahabah's vitae? Please pray for us both to achieve Afiyah in chastity.

Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
Sister-in-Islam,
It is encouraging to note that you are willing to go so far for the sake of another Muslim. May Allah Ta'ālā bless you tremendously for your efforts. The Holy Prophet (sallallahu alaihi wa sallam) said:
مَنْ كَانَ فِي حَاجَةِ أَخِيهِ كَانَ اللَّهُ فِي حَاجَتِهِ، وَمَنْ فَرَّجَ عَنْ مُسْلِمٍ كُرْبَةً فَرَّجَ اللَّهُ عَنْهُ كُرْبَةً مِنْ كُرُبَاتِ يَوْمِ الْقِيَامَةِ 
Whoever fulfils the needs of his brother, Allah will fulfil his needs; whoever brought his (Muslim) brother out of a discomfort, Allah will bring him out of the discomforts of the Day of Resurrection [Sahih al-Bukhari, 2442, Chapter: A Muslim should not oppress another Muslim]
Choosing a spouse is one of the greatest decisions a person will face during their life. A successful marriage may result in a life of happiness and prosperity, whereas a wrong decision can lead to a life of dismay and sorrow.
Islam emphasizes that one should look for a good match in all aspects before making a final decision about marriage.[1] It is also encouraged to seek out a partner who is an ardent follower of deen. The Holy Prophet (sallallahu alaihi wa sallam) said:
إِذَا أَتَاكُمْ مَنْ تَرْضَوْنَ خُلُقَهُ وَدِينَهُ فَزَوِّجُوهُ
If there comes to you one with whose character and religious commitment you are pleased, then marry (your children) to him. [Sunan ibn Majah, 1967, The Book of Nikah]
In any choice of marriage, there will be positive aspects as well as negative aspects. No marriage partner is 100% perfect. Decisions are based on what is probably the best. If you feel you can tolerate being with the person in reference and you can bear with all the challenges that come along with it then perform istikharah and seek guidance and goodness from Allah Ta'ālā before making a decision.
May Allah Ta'ālā grant you success in this life and the hereafter. Ameen.
And Allah Ta’āla Knows Best
