Allah allowed divorce after the marriage contract and before consummating the marriage. Ibn `Abbas, Tawus, Ibrahim and Al-Hasan Al-Basri said that `touched' (mentioned in the Ayah) means sexual intercourse. The husband is allowed to divorce his wife before consummating the marriage or giving the dowry if it was deferred.
Allah commands the husband to give the wife (whom he divorces before consummating the marriage) a gift of a reasonable amount, the rich according to his means and the poor according to his means, to compensate her for her loss. Al-Bukhari reported in his Sahih that Sahl bin Sa`d and Abu Usayd said that Allah's Messenger ﷺ married Umaymah bint Sharahil. When she was brought to the Prophet he extended his hand to her, but she did not like that. The Prophet then ordered Abu Usayd to provide provisions for her along with a gift of two garments.
