Prophet Hud - 11:113 Do not sympathize with the wrongdoers and do not support them, lest the Fire touch you. You have no friends except Allah, then you will not be helped.
The friends of the believers:
The Kneeling/45:19 They cannot ward off from you anything from Allah. The wrongdoers are each other´s friends. And Allah is the friend of the righteous.

The Table Spread/5:55 Your true friends are Allah and His Messenger and the believers who observe the prayer and pay the zakat humbly.
The Table Spread/5:56 Whoever takes as friends Allah and His messenger and the believers, know that Allah´s party will prevail.

The Woman Who Is Examined/60:8 Allah does not forbid you to do good to those who do not fight you for the sake of religion and do not drive you out of your homes, and to do justice to them. Allah loves those who do justice.

The Spoils of War/8:72 Those who believe and migrate in the Way of Allah and strive hard with their wealth and their lives and those who shelter them and help them are friends of one another. Those who believe but do not emigrate with you, you are not responsible for them until they emigrate. But if they ask you for help on account of their religion, you should help them, provided it is not against a people with whom you have an agreement. Allah is All-Seeing of what you do.

The Repentance/9:71 The believing men and the believing women are friends of one another. They enjoin good, forbid evil, observe the prayer, pay the zakat, and follow Allah and His messenger. Allah will have mercy on them. Allah is Superior, Wise.
The Repentance/9:16 Do you think that you will be left until Allah knows and distinguishes between those among you who strive hard for Him and those who take none as close friends except Allah and His Messenger and the believers? Allah is All-Knowing of what you do.

The Women/4:144 Believers, leave the believers and do not take the disbelievers as friends. Do you want to give Allah a proof to use against you!

The Family Of Imran/3:28 Let not the believers leave the believers and take the disbelievers as friends. Whoever does that has nothing to do with Allah. Except when you fear them. Allah warns you about Himself. The return is to Allah.

The Cow/2:257 Allah is the sovereign and the friend of those who believe; He brings them out of darkness into light. But the friends of those who disbelieve are fierce men; they bring them out of light into darkness. They are the people of the Fire, they will abide therein forever.
