قُلْ مَا كُنتُ بِدْعًۭا مِّنَ ٱلرُّسُلِ وَمَآ أَدْرِى مَا يُفْعَلُ بِى وَلَا بِكُمْ ۖ إِنْ أَتَّبِعُ إِلَّا مَا يُوحَىٰٓ إِلَىَّ وَمَآ أَنَا۠ إِلَّا نَذِيرٌۭ مُّبِينٌۭ
Say: I am no new thing among the messengers (of Allah), nor know I what will be done with me or with you. I do but follow that which is inspired in me, and I am but a plain warner.
