Please send me the authentic procedure of khul‘ah as prescribed in the Holy Qur’an and Hadith. A scholar who has studied from Madinah issued a girl khul‘ah letter one-sidedly. This scholar resides in USA and comes from Ghana. He did not contact the husband or his family. The girl told the scholar that her husband is in Pakistan studying. The girl claimed to have contacted her husband before taking khul‘ah from scholar. Is this khul‘ah correct or allowable from Islamic point of view?
