۞قُلۡ إِنَّمَآ أَعِظُكُم بِوَٰحِدَةٍۖ أَن تَقُومُواْ لِلَّهِ مَثۡنَىٰ وَفُرَٰدَىٰ ثُمَّ تَتَفَكَّرُواْۚ مَا بِصَاحِبِكُم مِّن جِنَّةٍۚ إِنۡ هُوَ إِلَّا نَذِيرٞ لَّكُم بَيۡنَ يَدَيۡ عَذَابٖ شَدِيدٖ
Qul innamaaa a'izukum biwaahidatin an taqoomoo lillaahi masnaa wa furaadaa summa tatafakkaroo; maa bisaahibikum min jinnah; in huwa illaa nazeerul lakum baina yadai 'azaabin shadeed
English Translation
Say, "I only advise you of one [thing] - that you stand for Allah, [seeking truth] in pairs and individually, and then give thought." There is not in your companion any madness. He is only a warner to you before a severe punishment
