WORKING FOR THE EVERLASTING LIFE H 67 "A wise person is one who guards and restrains himself from that which is harmful and strives for that which will benefit him after death. The foolish one is he who gives into his cravings and seeks from Allah the fulfillment of his futile desires." R PARA 67 Tirmidhi with a chain up to Shaddad son of Aus who related that the Prophet, praise and peace be upon him, said this.
