﴿ وَلَٰكِنَّآ أَنشَأْنَا قُرُونًۭا فَتَطَاوَلَ عَلَيْهِمُ ٱلْعُمُرُ ۚ وَمَا كُنتَ ثَاوِيًۭا فِىٓ أَهْلِ مَدْيَنَ تَتْلُوا۟ عَلَيْهِمْ ءَايَٰتِنَا وَلَٰكِنَّا كُنَّا مُرْسِلِينَ ﴾

“nay, but [between them and thee] We brought into being [many] generations, and long was their span of life. And neither didst thou dwell among the people of Madyan, conveying Our messages unto them: nay, but We have [always] been sending [Our message-bearers unto man].”
