Forsake their sides from (their) beds; they call their Lord (in) fear and hope, and out of what We have provided them they spend.

4:34
[The] men (are) protectors of the women because (has) bestowed Allah some of them over others and because they spend from their wealth. So the righteous women (are) obedient, guarding in the unseen that which (orders) them to guard (by) Allah. And those (from) whom you fear their ill-conduct then advise them, and forsake them in the bed and [finally] strike them. Then if they obey you then (do) not seek against them a way. Indeed, Allah is Most High, Most Great.

3:154
Then He sent down upon you from after the distress security - slumber overcoming a group of you, while a group certainly worried [them] (about) themselves thinking about Allah other than the truth - (the) thought (of) [the] ignorance. saying, "Is (there) for us from the matter any thing?" Say, "Indeed the matter all (of) it (is) for Allah." They hide in themselves what not they reveal to you, They say, "If was for us from the matter anything not we would have been killed here." Say, "If you were in your houses, surely (would have) come out those who - was decreed upon them [the] death towards their places of death. And that might test Allah what (is) in your breasts and that He may purge what (is) in your hearts. And Allah (is) All-Aware of what (is in) the breasts.
