2:101And when there came to them a messenger from God, confirming what they had, a faction of those who were given the Book threw the Book of God behind their backs, as if they do not know.

2:234As for those among you who die and leave widows behind, their widows shall wait by themselves for four months and ten days. When they have reached their term, there is no blame on you regarding what they might honorably do with themselves. God is fully acquainted with what you do.

2:240Those of you who die and leave wives behind—a will shall provide their wives with support for a year, provided they do not leave. If they leave, you are not to blame for what they do with themselves, provided it is reasonable. God is Mighty and Wise.

2:255God! There is no god except He, the Living, the Everlasting. Neither slumber overtakes Him, nor sleep. To Him belongs everything in the heavens and everything on earth. Who is he that can intercede with Him except with His permission? He knows what is before them, and what is behind them; and they cannot grasp any of His knowledge, except as He wills. His Throne extends over the heavens and the earth, and their preservation does not burden Him. He is the Most High, the Great.
