[If you do so,] behold, between you and the person for which there was enmity will be as though he were a sympathetic friend.”[^3] Therefore, we must respond in a nice way to one who says something bad as this goodness would lead to the stubborn enemy having a change of heart and inclining such that he would become a close, loving friend! The A`immah (as) and the Noble Prophet (S) were the embodiment of this verse and it is through their love that they were able to humble the enemies.
“Silatul Rahm (the act of the keeping the family bonds strong) enable the cities to be fortified and increases the life span.” This is another physical act related to the world, however it is not clear how the life span increases through maintaining family ties.
It is important to keep in mind that all types of worship and acts of transgression carry these forms of effects with them. It is possible that after committing a sin, a person would repent and Allah (SwT) would accept his forgiveness, however the effect of that sin remains with the person in the physical world. Thus, the repentance for a sin merely takes away the effect of the act in the spiritual realm, however its spiritual effects remain for a time period.
This is similar to poison which enters into a person's body and is not immediately taken out of the body forcing the person to ingest an antibody so that the effects of the poison do not stay with the person. In the tradition quoted, we see that it refers to two effects of one's actions in the physical realm. If the society were to pay attention to these effects, then they would definitely correct themselves much quicker than the current pace of reformation.
