Imam Ali (as): Imam Ali (AS) said to his son al-Hasan (AS): O my son, do not leave anything of this world behind you, as it could fall into the hands of two types of people: Either a person who uses it in obeying Allah, in which case, he will acquire virtue through what was evil for you, or it will be a person who uses it in disobeying Allah and in that case he will be earning evil with what you collected for him and so you will be assisting him in his sinfulness; and neither of these two deserves to be preferred by you over yourself.
