2 verses have
siblings
in Edition Clear Qur'an by Talal Itani / At-Tawba (The Repentance)

9:23O you who believe! Do not ally yourselves with your parents and your siblings if they prefer disbelief to belief. Whoever of you allies himself with them—these are the wrongdoers.

9:24Say, “If your parents, and your children, and your siblings, and your spouses, and your relatives, and the wealth you have acquired, and a business you worry about, and homes you love, are more dear to you than God, and His Messenger, and the struggle in His cause, then wait until God executes His judgment.” God does not guide the sinful people.
