Righteous leadership and moral example

وَٱلَّذِينَ يَقُولُونَ رَبَّنَا هَبْ لَنَا مِنْ أَزْوَٰجِنَا وَذُرِّيَّـٰتِنَا قُرَّةَ أَعْيُنٍ وَٱجْعَلْنَا لِلْمُتَّقِينَ إِمَامًا

And those who say, "Our Lord, grant us from among our wives and offspring comfort to our eyes and make us a leader [i.e., example] for the righteous."
