إِنَّمَا ٱلْمُؤْمِنُونَ ٱلَّذِينَ ءَامَنُوا۟ بِٱللَّهِ وَرَسُولِهِۦ ثُمَّ لَمْ يَرْتَابُوا۟ وَجَٰهَدُوا۟ بِأَمْوَٰلِهِمْ وَأَنفُسِهِمْ فِى سَبِيلِ ٱللَّهِ ۚ أُو۟لَٰٓئِكَ هُمُ ٱلصَّٰدِقُونَ
The (true) believers are those only who believe in Allah and His messenger and afterward doubt not, but strive with their wealth and their lives for the cause of Allah. Such are the sincere.

Narrated Ibn `Abbas:
The Prophet (ﷺ) said, "If somebody sees his Muslim ruler doing something he disapproves of, he should be patient, for whoever becomes separate from the Muslim group even for a span and then dies, he will die as those who died in the Pre-lslamic period of ignorance (as rebellious sinners). (See Hadith No. 176 and 177)
