وَإِن تُكَذِّبُوا فَقَدْ كَذَّبَ أُمَمٌ مِّن قَبْلِكُمْ وَمَا عَلَى الرَّسُولِ إِلَّا الْبَلَاغُ الْمُبِينُ
﴿١٨﴾
سورة العنكبوت
(29/18) And if you deny (belie), nations before you had indeed denied (belied). Nothing (no responsibility) on the Messenger but a plain conveying (of the Message).
Surah Al-Ankabut
