Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: "Indeed, Allah, the Mighty and Majestic, will question everyone whom He made responsible for a flock (of people) about those in his charge: did he establish the command of Allah among them, or did he neglect it? So much so that a man will even be questioned about the members of his household."
