Is a wife considered sinful for refusing and avoiding marital relations during her pregnancy due to severe morning sickness that makes her detest her husband and his scent, knowing that this refusal is beyond her control?

If the wife is harmed by intercourse, a harm that is unbearable during the morning sickness period, then she is permitted to refuse to the extent necessary to avert the harm. However, if the harm is slight and normally bearable, then she must be patient and endure it to preserve the husband's right; otherwise, she would be sinful, for the Prophet, peace and blessings be upon him, said: "If a woman spends the night forsaking her husband's bed, the angels curse her until the morning." It is permissible for the wife to gently persuade her husband to reduce intercourse until the morning sickness period ends.
