have baby and last week told me she is used pregnant pills I was very
upset for lie after lie, could you tell me how big is sins for using
pills not once twice and lying to me and what should she do for doing
thing against your husband
Answer
All perfect praise be to Allaah, The Lord of the Worlds. I testify
that there is none worthy of worship except Allaah, and that
Muhammadis His slave and Messenger.
Having children is the right of both husband and wife, and it is not
permissible for one of them to prevent the other from this right
without his/her permission as we clarified in Fatwa 87376.
Therefore, if your wife had used contraceptive pills without your
permission then she has made a mistake, and if she did so while
knowing its ruling, then she is sinful. Moreover, lying to her husband
in order to prevent him from his right is another sin. So, she must
repent to Allaah and seek the pardon of her husband.For more benefit
about the conditions of sincere repentance, she must obey her husband
and not take these pills without his permission.
Allaah Knows best.
