Al-Hashr • EN-TAFSIR-IBN-ABBAS
﴿ ذَٰلِكَ بِأَنَّهُمْ شَآقُّوا۟ ٱللَّهَ وَرَسُولَهُۥ ۖ وَمَن يُشَآقِّ ٱللَّهَ فَإِنَّ ٱللَّهَ شَدِيدُ ٱلْعِقَابِ ﴾
“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!”
(That) exile and punishment (is because they were opposed to Allah and His messenger) concerning Religion; (and whoso is opposed to Allah) in the matter of religion and shows enmity towards Him, ((for him) verily Allah is stern in reprisal) in the life of the world as well as in the Hereafter.
