contentment
٤٥١. وَقَالَ (عليه ‏السلام): زُهْدُكَ فِي رَاغِبٍ فِيكَ نُقْصَانُ حَظٍّ، وَرَغْبَتُكَ فِي زَاهِدٍ فِيكَ ذُلُّ نَفْسٍ.
451. Amīr al-mu’minīn, peace be upon him, said: Your turning away from him who inclines towards you is a loss of your share of advantage while your inclining towards him who turns away from you is humiliation for yourself.
