Surat At-Tawbah - سورة التوبة

وَأَذَانٌ مِّنَ اللَّهِ وَرَسُولِهِ إِلَى النَّاسِ يَوْمَ الْحَجِّ الْأَكْبَرِ أَنَّ اللَّهَ بَرِيءٌ مِّنَ الْمُشْرِكِينَ ۙ وَرَسُولُهُ ۚ فَإِن تُبْتُمْ فَهُوَ خَيْرٌ لَّكُمْ ۖ وَإِن تَوَلَّيْتُمْ فَاعْلَمُوا أَنَّكُمْ غَيْرُ مُعْجِزِي اللَّهِ ۗ وَبَشِّرِ الَّذِينَ كَفَرُوا بِعَذَابٍ أَلِيمٍ

Muhsin Khan: And a declaration from Allah and His Messenger to mankind on the greatest day (the 10th of Dhul-Hijjah - the 12th month of Islamic calendar) that Allah is free from (all) obligations to the Mushrikun (see V.2:105) and so is His Messenger. So if you (Mushrikun) repent, it is better for you, but if you turn away, then know that you cannot escape (from the Punishment of) Allah. And give tidings (O Muhammad SAW) of a painful torment to those who disbelieve.
