27:21
لَأُعَذِّبَنَّهُۥ عَذَابًا شَدِيدًا أَوْ لَأَا۟ذْبَحَنَّهُۥٓ أَوْ لَيَأْتِيَنِّى بِسُلْطَـٰنٍ مُّبِينٍ
la-uʿadhibannahu ʿadhāban shadīdan aw laādh'baḥannahu aw layatiyannī bisul'ṭānin mubīnin
I will punish him severely, or kill him, unless he brings me a convincing excuse for his absence.’
"I will surely punish him with a severe torment, or slaughter him, unless he brings me a clear reason."
