According to this Question - Why are Muslim women prohibited from marrying non-Muslims while Muslim men are allowed to? muslim men can marry non muslim women.
But i had read a hadeeth which said that we must not promote this thing because the laws keep on getting diluted as time passes by i.e. now the muslim men might be converting their wives to Islam but maybe in later years they might not.
Can someone help me clarify this by finding that hadeeth?
