qurrata a'yun - comfort of our eyes

And those who pray, "Our Lord! Grant unto us spouses and offspring who will be the comfort of our eyes, and give us (the grace) to lead the righteous."

وَالَّذِينَ يَقُولُونَ رَبَّنَا هَبْ لَنَا مِنْ أَزْوَاجِنَا وَذُرِّيَّاتِنَا قُرَّةَ أَعْيُنٍ وَاجْعَلْنَا لِلْمُتَّقِينَ إِمَامًا

Al Quran, Al-Furqan 25:74
