390. Amir al-mu'minin, peace be upon him, said: The believer's time has three periods: The period when he is in communion with Allah; the period when he manages for his livelihood; and the period when he is free to enjoy what is lawful and pleasant. It does not behove a wise person to be away (from his house) save for three matters, namely for purposes of earning, or going for something for the next life or for enjoying what is not prohibited.
