Question
I heard in my childhood that my mother breastfed my cousin (father's nephew). However, as we grew up, this rumor faded, and I have been engaged to that cousin and am likely to marry him in a few months. Now, I have seen thrice in a dream that I am marrying my brother. It put me in severe doubts and revived the rumor related to the breastfeeding. I asked my mother and aunt (cousin's mother), they say that they do not remember. If it happened, it happened once or twice. Please guide me in this regard.
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 sallallaahu `alayhi wa sallam ( may Allaah exalt his mention ) is His slave and Messenger.
If there is any doubt about this breastfeeding, then this does not prove the prohibition, which means that it is not forbidden for your cousin to marry you.
