Ali bin al-Mubark al-Hna'iy علي بن المبارك الهنائي · Divorce (Kitab Al-Talaq)

Imran ibn Husayn was asked about a person who divorces his wife, and then has intercourse with her, but he does not call any witness to her divorce nor to her restoration. He said: You divorced against the sunnah and took her back against the sunnah. Call someone to bear witness to her divorce, and to her return in marriage, and do not repeat it.
