Abu Hurairah (May Allah be pleased with him) reported: Messenger of Allah (PBUH) said, "It is not lawful for a woman to observe (voluntary) fasting without the permission of her husband when he is at home; and she should not allow anyone to enter his house without his permission.".[Al-Bukhari and Muslim].
Commentary:
It lays down a principle for a wife that performing Nawafil (voluntary acts of worship) at the cost of the husband rights is not permissible. |
