Surah Ar-Rum — Ayah 10 (30:10)
ثُمَّ كَانَ عَٰقِبَةَ ٱلَّذِينَ أَسَٰٓـُٔواْ ٱلسُّوٓأَىٰٓ أَن كَذَّبُواْ بِـَٔايَٰتِ ٱللَّهِ وَكَانُواْ بِهَا يَسۡتَهۡزِءُونَ ١٠
English translation (Saheeh International)
Then the end of those who did evil was the worst [consequence] because they denied the signs of Allāh and used to ridicule them.
Brief commentary
Then, the outcome of those who did evil deeds i.e. idolatry and sins, was an extremely evil outcome. It was because they rejected the signs of Allah and would mock at and make fun of them.
