Assalamu Alaikum Mufti Sahab

I would like to fast on Mondays and thursdays . I usully check with my wife a day before fasting to see if she has anything else in mind. Some times she tells me not to fast because she dosnt feel like cooking or eating alone If I am fasting. She would like to fast too but she is week due to health issues and nursing our new born. I was concered that she will be held accountable if she says no to me fasting.I love my wife and I am concerned for her akhira . I feel guilty the day I am not fasting eventhough its voluntary fast .Please Advice .

Jazakallah Khair
