Is it permissible for a husband to use the same miswak which his wife is using? Similarly towel and comb or they must use separate items?
According to Shariah, there is no problem. However, there is also no harm if they are kept separate due to personal cleanliness, but doing so out of pride is bad.
Hadhrat Ayesha (رضى الله عنها) presented miswak chewed by her teeth to the holy Prophet Muhammad (صلى الله عليه وسلم) in his deathbed and the holy Prophet Muhammad (صلى الله عليه وسلم) used it.
Allah (Subhana Wa Ta’ala) knows Best
