Suhail bin Abu Salih narrates from his father: "I asked twelve Companions about a person who takes an oath of abstinence (ila’), and these individuals gave the same answer: Nothing will be imposed upon him until four months have passed. Then it will depend on (the husband's decision); if he returns (to his wife), then (it is fine), otherwise he should divorce her."
