Seeking Permission From Ones Husband
Abu Hurayrah (radi Allahu anhu) reported that the Messenger of Allah (sal Allahu alaihi wa sallam) 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.”
[Sahih al-Bukhari and Muslim]
This hadith lays down a principle for a wife that performing Nawafil (voluntary acts of worship) at the cost of the husband rights is not permissible.
And Allah Knows Best!
