Surat Al-'An`ām - سورة الأنعام

قُلْ أَرَأَيْتَكُمْ إِنْ أَتَاكُمْ عَذَابُ اللَّهِ أَوْ أَتَتْكُمُ السَّاعَةُ أَغَيْرَ اللَّهِ تَدْعُونَ إِن كُنتُمْ صَادِقِينَ

Muhsin Khan: Say (O Muhammad SAW): "Tell me if Allah's Torment comes upon you, or the Hour comes upon you, would you then call upon any one other than Allah? (Reply) if you are truthful!"
