And (as for) those of you who die and leave wives behind, they should keep themselves in waiting for four months and ten days; then when they have fully attained their term, there is no blame on you for what they do for themselves in a lawful manner; and Allah is aware of what you do.

So when Musa had fulfilled the term, and he journeyed with his family, he perceived on this side of the mountain a fire. He said to his family: Wait, I have seen a fire, maybe I will bring to you from it some news or a brand of fire, so that you may warm yourselves.

Do you not see that Allah makes the night to enter into the day, and He makes the day to enter into the night, and He has made the sun and the moon subservient (to you); each pursues its course till an appointed time; and that Allah is Aware of what you do?

And Allah does not respite a soul when its appointed term has come, and Allah is Aware of what you do.
