The obligation of the father to guide family towards piety

وَكَانَ يَأْمُرُ أَهْلَهُۥ بِٱلصَّلَوٰةِ وَٱلزَّكَوٰةِ وَكَانَ عِندَ رَبِّهِۦ مَرْضِيًّۭا

He used to enjoin on his people Prayer and Charity, and he was most acceptable in the sight of his Lord.

وَأْمُرْ أَهْلَكَ بِٱلصَّلَوٰةِ وَٱصْطَبِرْ عَلَيْهَا ۖ لَا نَسْـَٔلُكَ رِزْقًۭا ۖ نَّحْنُ نَرْزُقُكَ ۗ وَٱلْعَٰقِبَةُ لِلتَّقْوَىٰ

Enjoin prayer on thy people, and be constant therein. We ask thee not to provide sustenance: We provide it for thee. But the (fruit of) the Hereafter is for righteousness.
