in Edition Clear Qur'an by Talal Itani / An-Nisaa (The Women)

4:5Do not give the immature your money which God has assigned to you for support. But provide for them from it, and clothe them, and speak to them with kind words.

4:8If the distribution is attended by the relatives, and the orphans, and the needy, give them something out of it, and speak to them kindly.

4:19O you who believe! It is not permitted for you to inherit women against their will. And do not coerce them in order to take away some of what you had given them, unless they commit a proven adultery. And live with them in kindness. If you dislike them, it may be that you dislike something in which God has placed much good.

4:114There is no good in much of their private counsels, except for him who advocates charity, or kindness, or reconciliation between people. Whoever does that, seeking God’s approval, We will give him a great compensation.
