As salamu aleikum,
I would like to know if my fasting is invalid if I have fed my Muslim not fasting family members and guest during Ramadan. One friend told me that act would invalidate my fast, since we are not allowed to feed any adult healthy Muslims – even our own children or guest- during Ramadan if they do not fast.
wa `alaykum salam,
Your fasting is valid, but your action is disliked, unless the person could not fast for valid reasons.
