41:13
فَإِنْ أَعْرَضُوا۟ فَقُلْ أَنذَرْتُكُمْ صَـٰعِقَةً مِّثْلَ صَـٰعِقَةِ عَادٍ وَثَمُودَ
fa-in aʿraḍū faqul andhartukum ṣāʿiqatan mith'la ṣāʿiqati ʿādin wathamūda
If they turn away, say, ‘I have warned you about a blast like the one which struck 'Ad and Thamud:
But if they turn away, then say (O Muhammad صلى الله عليه وسلم): "I have warned you of a Sâ‘iqah (a destructive awful cry, torment, hit, a thunderbolt) like the Sâ‘iqah which overtook ‘Âd and Thamûd (people)."
