﴿ ۞ قُلْ إِنَّمَآ أَعِظُكُم بِوَٰحِدَةٍ ۖ أَن تَقُومُوا۟ لِلَّهِ مَثْنَىٰ وَفُرَٰدَىٰ ثُمَّ تَتَفَكَّرُوا۟ ۚ مَا بِصَاحِبِكُم مِّن جِنَّةٍ ۚ إِنْ هُوَ إِلَّا نَذِيرٌۭ لَّكُم بَيْنَ يَدَىْ عَذَابٍۢ شَدِيدٍۢ ﴾

“Say: “I counsel you one thing only: Be [ever­ conscious of] standing before God, whether you are in the company of others or alone; and then bethink yourselves [that] there is no madness in [this pro­phet,] your fellow-man: he is only a warner to you of suffering severe to come.””

(Say) to the disbelievers of Mecca, O Muhammad: (I exhort you unto one thing only) with �there is no deity save Allah�: (that ye awake, for Allah's sake, by twos and singly, and then reflect) upon whether Muhammad (pbuh) is a magician, fortune teller, a liar or madman: (There is no madness in your comrade) in your Prophet. (He) Muhammad (pbuh) (is naught else than a warner) a warning Messenger (unto you in face of a terrific doom) on the Day of Judgement if you reject faith.
