With regard to one who is obliged to fast:
1 â If he has intercourse with his wife during the day in Ramadaan, one or more times on one day, then he must offer one expiation. If he had intercourse on several days then he must offer multiple expiations, the same number as the days on which he had intercourse.
2 â He must offer expiation for having intercourse even if he was unaware of the fact that he would have to offer expiation for having intercourse.
3 â The wife must also offer expiation for having intercourse if she willingly went along with her husband in that. But if she was forced then she does not have to do anything.
4 â It is not permissible to give money instead of feeding a poor person, and that is not sufficient.
5 â It is permissible to feed one poor person half a saaâ on behalf of himself and half a saaâ on behalf of his wife. That will be considered to be one of the sixty poor persons who must be fed on behalf of them both.
6 â it is not permissible to give it all to one poor person, or to a charitable organization etc., because they may not distribute it to sixty poor persons. The believer must strive to discharge his duty with regard to expiations and other obligations.
And Allaah is the Source of strength. May Allaah send blessings and peace upon our Prophet Muhammad and his family and companions.
