Question:
If one or two divorces occur, who is responsible for maintenance and housing during the waiting period?
Answer:
In the case of revocable divorce, all expenses and housing during the waiting period will be the responsibility of the husband. The Prophet Muhammad (peace be upon him) said:
إنما النفقة والسكنى للمرأة إذا كان لزوجها عليها الرجعة
"In the case of revocable divorce, the woman is entitled to maintenance and housing."
Reference: (Sunan an-Nasa'i: 3403, its chain is authentic)
There is consensus among Muslims on this matter.
❀ Hafiz Baghawi (may Allah have mercy on him)
Reference: (516 AH)
states:لا خلاف بين أهل العلم فى المعتدة الرجعية أنها تستحق النفقة، والسكنى على زوجها
"There is no disagreement among scholars that the maintenance and housing of a woman undergoing the waiting period of a revocable divorce is the responsibility of the husband."
Reference: (Sharh as-Sunnah: 302/9)
