قُلْ اِنَّمَاۗ اَعِظُكُمْ بِوَاحِدَۃٍ۰ۚ اَنْ تَقُوْمُوْا لِلہِ مَثْنٰى وَفُرَادٰى ثُمَّ تَتَفَكَّرُوْا۰ۣ مَا بِصَاحِبِكُمْ مِّنْ جِنَّۃٍ۰ۭ اِنْ ہُوَاِلَّا نَذِيْرٌ لَّكُمْ بَيْنَ يَدَيْ عَذَابٍ شَدِيْدٍ۴۶
Qul innama aAAithukum biwahidatin an taqoomoo lillahi mathna wafurada thumma tatafakkaroo ma bisahibikum min jinnatin in huwa illa natheerun lakum bayna yaday AAathabin shadeedin
