Is it okay to marry ones step-sister?

Mu' meneen Brothers and Sisters,

As Salaam Aleikum wa Rahmatullahi wa Barakatuh. (May Allah's Peace, Mercy and Blessings be upon all of you)

One of our brothers/sisters has asked this question:

Answer:

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.

Your Question: Is it okay to marry ones step-sister?
We assume that by the term ‘step-sister’ it would mean the relationship of a person whose mother married a man (or whose father married a woman) who already had a daughter from another marriage. 

 

A ‘step-sister’ (as opposed to a ‘half-sister’ who share the same biological parent) is not considered a mehram in Islam; thus it is absolutely permissible for one to marry their ‘step-sister’ if one wishes to do so, provided all the other conditions of marriage are fulfilled.

 

Your Question: What are the conditions of such a marriage, i.e. time living together.

There are absolutely no such conditions or restrictions as time living or spent together if one wishes to marry one’s ‘step-sister’; all the conditions that apply to any non-mehram eligible woman one wishes to marry would be applicable to the ‘step-sister’. 

Whatever written of Truth and benefit is only due to Allah’s Assistance and Guidance, and whatever of error is of me. Allah Alone Knows Best and He is the Only Source of Strength. Allah Alone Knows Best and He is the Only Source of Strength.

Your brother and well wisher in Islam,
