What are the rulings regarding reconciliation (rajʿah) and consensual divorce for an addict who does not provide for his family, and does the wife have the right to refuse?

If a husband divorces his wife fewer than three times, and the divorce was not for financial compensation, then it is a revocable divorce (ṭalāq rajʿī). Mere agreement to divorce does not make it an irrevocable divorce (ṭalāq bā’in). If the husband takes her back during her waiting period (ʿiddah), this is valid, and the marital relationship returns as it was.

However, if the harm from the husband persists, the wife has the right to refuse to return to his home until the harm ceases. She may also request divorce again, or seek Khulʿ from him by paying money or waiving a right. Khulʿ is permissible if the wife dislikes her husband due to his religiosity or character, and fears that she will not fulfill Allah's right, as Allah Almighty says: {But if you fear that they will not uphold the limits of Allah, then there is no blame upon either of them concerning what she gives to free herself.} Such matters are usually resolved before a Sharia judge.
