Mall ....Before reading the thread content, i really thought some ugly story in my mind(because that was what your title suggested)...
See what your MIL said was wrong...no doubt about it but you do not have to kill her for that...try to understand that if a person is making such comment then you being an educated person should realize his/her understanding(samaj ka) level and react according to that. Allah Ta'ala has blessed you with this naimat, be thankful to him rather than thinking negative about your mother in law.
Personally, if my MIL had said something like that to me then i would have just ignored the comment because a person with a very limited understanding can say such thing so there is no need to absorb so much negativitiy in this period. Try to relax and pray for yourself n your child.
thx falafel. i felt a bit better after readin ur comments. u r rite. ppl have been tellin me just let her talk.. but me being the sensitive (over) that i m, i cant get this out of my mind. ill try to think +ve. thanks alot.
