In Mottaqeen Sermon, Imam Ali (AS) explained: But the pious! In the world they possess superior virtues, their words are the truth, their cover is moderate, and they walk with humility and modesty, they cover their eyes from what God has made Haram, and dedicate their ears to useful knowledge, and in hard times or in good times, their state of mind (feeling) stays the same [1].
