SHAFAQNA – Imam Ali (AS) said: For the inferiority of this world it is enough to say that nowhere else God is disobeyed except in this world and except by abandoning it (disobedience of God) nothing can be attained from what is with God . We must know where we are, where we have come from, our account is safe, where we are going, our account is safe, and we descended through this arc with glory and magnificence; God willing we will ascend through the arc with glory and magnificence; but we are here (this world) for a few days.
This is the saying of Imam Ali (AS) in Nahjul Balaghah: There is no other world as inferior as to this world and there is no worse place than here (this world). Meaning, we have to be careful, when one is in prison, what can he expect? Imam (AS) said: There is no other world as inferior as and worse than this world. There are many preceding worlds, and there many worlds to follow, the worlds which God has created are not limited, we do not know their numbers.
Imam Ali (AS) who is aware of the past and the future, said: Neither in the past nor in the future, there was or will be a world as inferior as this world; sins are not committed in any other world except this world. We are in this world, we must be very careful, we must not expect that all of us be like Salman and Abuzar, if someone is like them the better, and if he is not, we need to guide him; but the aim is that when we know we live in a prison, must look after our tongues.
