What is the Shar'i ruling regarding repeated instances of divorce, and what is the Shar'i evidence for that? What is the ruling concerning a child born after the third divorce, if the wife is unlawful to the husband? What is the ruling concerning years of living together based on the fatwa of Sheikh Muhammad Bilal, may Allah have mercy on him? Is it permissible to rely on the fatwa of a single scholar when it contradicts the fatwas of other scholars, and is it permissible to adopt a fatwa from non-Sunni scholars on this matter?

It is established by the Quran, Sunnah, and the consensus of the Ummah that a wife is irrevocably divorced from her husband (she is not lawful for him until she marries another husband) if he divorces her three separate times. However, if he issues the three divorces at once, scholars differ on their validity. As for your specific case, the second and third divorces are valid, but the first divorce is problematic because it occurred during anger and involved issuing multiple divorces in a single utterance. We advise you to consult a Sharia court. The child is attributed to you even if the relationship was illicit, as long as you believed the marriage was valid or relied on the opinion of scholars. Regarding adopting the fatwa of one scholar or school of thought over another, we advise you to refer to Fatwa No. 38534. As for the years you lived with your wife, the sinfulness depends on your negligence in seeking the truth, or your search for a concession, or your knowledge of the reliability of the mufti.
