shahrukh khan said: non muslim ke liye dua kar sakte hain?
lemme sum it up...
remember how hazrat umer converted into islam? holy prophet (PBUH) prayed to God, (i dunno thre exact words, here's the summary)...
O God, umer ya abu-jehl mae se ek ko islam kabool kernay ke taufeeq farma...what happened after...how did the dua worked...is different story and does not relates to the original topic...so i'll leave it here...
point is...holy prophet (PBUH) prayed for hazrat umer when he was non-muslim...
so...it is ok to pray for a non-muslim...
