Imam Hasan Askari (as):

Kisi gham-raseedah (ghamgeen) insaan ke saamne khushi ka izhaar karna adab o tehzeeb ke khilaaf hai.
(Nuqoosh e Ismat, p602)

[Dost kapde ke oos pevand (Kapde ka tukda jo phate hue hisse par lagaya jata hai) ki tarah hai jise marammat ke liye lagaya jata hai—is ka qism, rang aur kapde (fabric) mein bilkul match hona zaroori hai. Is liye, aisa dost chuno jo kirdar aur aqeedat (values) mein bilkul tumhare jaisa ho.]
