Imam Ali (as): Imam Ali (AS) said to Kumayl ibn Ziyad an-Nakha'i: O Kumayl, enjoin your people to go out in the day and strive to adopt noble traits and to go out in the night and meet the needs of those who might be sleeping, for I swear by Him Whose hearing extends to all voices, if ever someone brings happiness to another's heart, Allah will create a special thing out of this happiness so that whenever any hardship befalls him it will come running like flowing water and drive away the hardship as wild camels are driven away.
