#Allah refuses brotherhood between muslims and unbelievers

“Do not marry polytheistic women until they believe; for a believing slave-woman is better than a free polytheist, even though she may look pleasant to you. And do not marry your women to polytheistic men until they believe, for a believing slave-man is better than a free polytheist, even though he may look pleasant to you. They invite you to the Fire while Allah invites you to Paradise and forgiveness by His grace. He makes His revelations clear to the people so perhaps they will be mindful.”

“Believers should not take disbelievers as guardians instead of the believers—and whoever does so will have nothing to hope for from Allah—unless it is a precaution against their tyranny. And Allah warns you about Himself. And to Allah is the final return.”

“O believers! Take neither Jews nor Christians as guardians—they are guardians of each other. Whoever does so will be counted as one of them. Surely Allah does not guide the wrongdoing people.”

“O believers! Do not take your parents and siblings as trusted allies if they choose disbelief over belief. And whoever of you does so, they are the true wrongdoers.”

“You will never find a people who truly believe in Allah and the Last Day loyal to those who defy Allah and His Messenger, even if they were their parents, children, siblings, or extended family. For those believers, Allah has instilled faith in their hearts and strengthened them with a spirit from Him. He will admit them into Gardens under which rivers flow, to stay there forever. Allah is pleased with them and they are pleased with Him. They are the party of Allah. Indeed, Allah’s party is bound to succeed.”
