سُورَةُ الحَشۡرِ
Surah Al-Hashr·59:4
ذَٰلِكَ بِأَنَّهُمْ شَاقُّوا اللَّهَ وَرَسُولَهُ ۖ وَمَنْ يُشَاقِّ اللَّهَ فَإِنَّ اللَّهَ شَدِيدُ الْعِقَابِ٤
this, because they cut themselves off from God and His Apostle: and as for him who cuts himself off from God and His Apostle - verily, God is severe in retribution!
