Surah 2. Al-Baqara, Ayah 226

I.e., during this period of grace.

 This ruling is called ilâ'. Ilâ' means that a husband vows not to be intimate with his wife because of a dispute or any other legitimate reason. The verse here says if it is four months or less and the husband keeps his vow, then he does not have to make up for breaking his vow (by feeding ten poor people, or fasting three days), otherwise he will need to make up for breaking his vow. If the vow is made for over four months, the wife has the right to seek divorce after four months. Ilâ' should be avoided altogether since it deprives the wife of her right to sexual satisfaction. Instead, counselling is a better alternative at the time of dispute.
