Why is it that in Islam, a widow must go through the mourning period of 4 months and 10 days ?

this answer is from a muslim:The rule is that a widow should remain in her husband’s house during this time because she is entitled to shelter and support while she makes plans and arrangements for her future, and also out of respect for her husband who has died. please dont take some of the other answers as truth because they just say stuff to make islam look bad.

Because they didn’t have pregnancy tests in the 7th century, and they had to make sure that she wasn’t pregnant before she could be remarried or move on with her life.

@Zuhal, this time period is based on how long it took to confirm a pregnancy at the time. A similar time period is required after a divorce, isn’t it? I said nothing derogatory about your religion – all I said was the reason for using this particular length of time.

Mohammed figures that it is about the right time to make sure she is not of the horny type before stoning any widow for lascivious conduct!!

That’s abiout the LAW OF THE LAND in several Muslim countries!
