﴿ وَلَمَّا وَرَدَ مَآءَ مَدْيَنَ وَجَدَ عَلَيْهِ أُمَّةًۭ مِّنَ ٱلنَّاسِ يَسْقُونَ وَوَجَدَ مِن دُونِهِمُ ٱمْرَأَتَيْنِ تَذُودَانِ ۖ قَالَ مَا خَطْبُكُمَا ۖ قَالَتَا لَا نَسْقِى حَتَّىٰ يُصْدِرَ ٱلرِّعَآءُ ۖ وَأَبُونَا شَيْخٌۭ كَبِيرٌۭ ﴾

“NOW WHEN he arrived at the wells of Madyan, he found there a large group of men who were watering [their herds and flocks]; and at some distance from them he came upon two women who were keeping back their flock. He asked [them]: “What is the matter with you?” They answered: “We cannot water [our animals] until the herdsmen drive [theirs] home - for [we are weak and] our father is a very old man.””
