Surah Al-Mu'minun — Ayah 67

لَا تَجْـَٔرُوا۟ ٱلْيَوْمَ ۖ إِنَّكُم مِّنَّا لَا تُنصَرُونَ

Do not cry out today. Indeed, by Us you will not be helped.

قَدْ كَانَتْ ءَايَـٰتِى تُتْلَىٰ عَلَيْكُمْ فَكُنتُمْ عَلَىٰٓ أَعْقَـٰبِكُمْ تَنكِصُونَ

My verses had already been recited to you, but you were turning back on your heels

أَفَلَمْ يَدَّبَّرُوا۟ ٱلْقَوْلَ أَمْ جَآءَهُم مَّا لَمْ يَأْتِ ءَابَآءَهُمُ ٱلْأَوَّلِينَ

Then have they not reflected over the Qur'an, or has there come to them that which had not come to their forefathers?

أَمْ لَمْ يَعْرِفُوا۟ رَسُولَهُمْ فَهُمْ لَهُۥ مُنكِرُونَ

Or did they not know their Messenger, so they are toward him disacknowledging?
