SHAFAQNA – It is narrated from Imam Sadeq (AS) who said: Be satisfied with what Allah (SWT) has allocated for you, and do no look at what others have, do not lose your heart to them, and do not wish to have those. Do not wish for things which you will not be able to have them. Therefore, the one who is satisfied (with what God has given him) will get full, and the one who is not satisfied, will never get full .
