4:23Forbidden for you are your mothers, your daughters, your sisters, your paternal aunts, your maternal aunts, your brother's daughters, your sister's daughters, your foster-mothers who nursed you, your sisters through nursing, your wives' mothers, and your stepdaughters in your guardianship—born of wives you have gone into—but if you have not gone into them, there is no blame on you. And the wives of your genetic sons, and marrying two sisters simultaneously. Except what is past. God is Oft-Forgiving, Most Merciful.

4:101When you travel in the land, there is no blame on you for shortening the prayers, if you fear that the disbelievers may harm you. The disbelievers are your manifest enemies.

4:112And whoever commits a mistake, or a sin, and then blames it on an innocent person, has taken a slander and a clear sin.
