If we go on this heedlessness...
If we go on this heedlessness, we will not know that test except that we know that whoever heads for the belief in Allah, the Exalted, and approaches the Most Holy Allah for a span of the hand is far away from the enjoyment of this world for a mile, and whatever he gets rid of the pleasures of this existence turns away from that which is below the belief in the Necessary Being (Allah). 1 al- Kafi: 8/207/347. Fear and Hope: Indeed, Allah, the Exalted, embraces might and mercy, wrath and pleasure.
So, His great wrath is according to His great mercy, His great punishment is according to His abundant reward. As His mercy is great, there is a hope that it will include the sinner. As His punishment is severe, fear of His wrath is certain. According, the believer must be between fear and hope because he does not know with which sin his punished and written in the record of sinners and does not know for which good act he is rewarded and regarded as one of the good- doers.
For this reason, he must always be careful of the sin to avoid it and looks for the good act to obtain its reward. al- Sâdiq, peace be on him said many traditions about the necessity of fear and hope for the believer and their dangers when man loses them. On fear, he said:” Fear Allah as if you had seen Him. If you do not see Him, surely, He sees you. If you thing that He does not see you, then you are an unbeliever.
