Quran 9:10 — Ultimatum (Bara'ah)

They never observe any rights of kinship towards any believer, nor do they uphold their covenants; these are the real transgressors.

[9:9] They traded away GOD's revelations for a cheap price. Consequently, they repulsed the people from His path. Miserable indeed is what they did!

[9:11] If they repent and observe the Contact Prayers (Salat) and give the obligatory charity (Zakat), then they are your brethren in religion. We thus explain the revelations for people who know.
