﴿ فَأَرْسَلْنَا فِيهِمْ رَسُولًۭا مِّنْهُمْ أَنِ ٱعْبُدُوا۟ ٱللَّهَ مَا لَكُم مِّنْ إِلَٰهٍ غَيْرُهُۥٓ ۖ أَفَلَا تَتَّقُونَ ﴾

“and [every time] We sent unto them an apostle from among themselves, [he told them:] “Worship God [alone]: you have no deity other than Him. Will you not, then, become conscious of Him?””

And We sent among them a messenger of their own namely Hūd saying ‘Worship God! You have no other god besides Him. Will you not then be wary?’ of His punishment and become believers?
