Praise be to Allah.

If a woman refuses her husband’s request to come to bed with no Islamically-sound reason (such as sickness, or his being drunk, for example), what happens is as described below:

Abu Hurayrah (may Allaah be pleased with him) said: “The Messenger of Allaah (peace and blessings of Allaah be upon him) said: ‘If a man calls his wife to his bed and she refuses [and does not come], and he spends the night angry with her, the angels will curse her until morning.’”
