And if you fear that you will not deal justly with the orphan girls, then marry those that please you of [other] women, two or three or four. But if you fear that you will not be just, then [marry only] one or those your right hand possesses. That is more suitable that you may not incline [to injustice].
(Quran 4:3)
You can never be equitable in dealing with more than one wife, no matter how hard you try. Therefore, do not be so biased as to leave one of them hanging. If you correct this situation and maintain righteousness, Allah is Forgiver, Most Merciful.
(Quran 4:129)

Have you considered him who denies the religion? It is he who mistreats the ORPHAN. And does not encourage the feeding of the poor. So woe to those who pray. Those who are heedless of their prayers. Those who put on the appearance. And withhold the assistance.
(Quran 107:1-7)

And they feed, for the love of Him, the POOR, and the orphan, and the captive. We only feed you for the sake of Allah. We want from you neither compensation nor gratitude. We dread from our Lord a frowning grim day. So Allah will protect them from the ills of that Day and will grant them radiance and joy. And will reward them for their patience with a garden and silk.
(Quran 76:8-12)

He frowned and turned away. When the BLIND man approached him. But how do you know? Perhaps he was seeking to purify himself. Or be reminded, and the message would benefit him. But as for him who was indifferent. You gave him your attention. Though you are not liable if he does not purify himself. But as for him who came to you seeking. In awe. To him you were inattentive. Do not. This is a Lesson. Whoever wills, shall remember it.
(Quran 80:1-12)

We made a covenant with the Children of Israel: “Worship none but Allah, and be good to parents, and relatives, and orphans, and the NEEDY; and speak nicely to people, and pray regularly, and give alms.” Then you turned away, except for a few of you, recanting.
(Quran 2:83)
