Namaz isn’t the only farz, so are other things like how a woman should dress. By your arguement, if a muslim woman isn’t dressed in accordance to the quran/ sunnah then she shouldnt be as obsessed with paying attention to her fasts?
If you were careless about your fluid intake, then that is really your fault and it was not right for you to be negligent about it.
Most woman do go for regular check ups during their pregnancy, i think they’d know from that is something was wrong…
an article posted previously in this thread (from babycentre) mentions that there is no sound evidence to suggest that fasting does adverselfy affect the baby, why do we jump to assume otherwise?
And we shouldn’t decide what to follow/ avoid based on what non-mulims think. I’m sure to many of them the concept of hijab is extreme, uss ko bhi islam se nikaal deiN kya just to please 'em?
sawal ye nahi hai ke farz ko poora kya ja raha hai ke nahi, sawal ye hai ke kya hum kissi farz ehkaam ko farz se kum na samhajne lage, God Forbid.
