Surah Al-Qasas (The Stories), Verse 23

وَلَمَّا وَرَدَ مَآءَ مَدْیَنَ وَجَدَ عَلَیْهِ اُمَّةً مِّنَ النَّاسِ یَسْقُوْنَ وَوَجَدَ مِنْ دُوْنِهِمُ امْرَاَتَیْنِ تَذُوْدٰنِ قَالَ مَا خَطْبُكُمَا قَالَتَا لَا نَسْقِیْ حَتّٰی یُصْدِرَ الرِّعَآءُ وَاَبُوْنَا شَیْخٌ كَبِیْرٌ ۟

Wa lammaa warada maaa'a Madyana wajada 'alaihi ummatam minannaasi yasqoona wa wajada min doonihimum ra ataini tazoodaani qaala maa khatbukumaa qaalataa laa nasqee hatta yusdirar ri'aaa'u wa aboonaa shaikhun kabeer

“And when he arrived at the watering (place) in Madyan, he found there a group of men watering (their flocks), and besides them he found two women who were keeping back (their flocks). He said: "What is the matter with you?" They said: "We cannot water (our flocks) until the shepherds take back (their flocks): And our father is a very old man."”
