The meaning of “…that which is with Allah” is His Divine Reward; close proximity to Him, and His blessings. Without doubt, if we request these from Him, then Allah (SwT) will definitely love us. However, we are told that when a person begins to show affection for another person due to the material pleasures which the person has (and that this person wants), then he should not pay any attention to such a person.
Without doubt, the stingy person lives his life by being miserly and this negative trait would lead such a person to develop closeness to people who are not interested in the material world (to take what they have). Without doubt, if a person wishes to protect his position, status and worth, then he must disregard that which the people have in their possession! Throughout the course of history, amazing events have taken place in these regards.
We read stories of rulers who killed those close to them and have even heard of people who have killed their own brothers just to protect their reign! For example when Sultan Muhammad Fatih, one of the ‘Uthmani (Ottoman) rulers became the emperor, he ordered all his brothers to be killed since he feared that they would be a threat to his rule! After the reign of Sultan Muhammad Fatih, it became the norm amongst the ‘Uthmani rulers to begin their reign by killing all of their brothers!
In relation to one of the Parthian kings, it is mentioned that when he reached to kingship, he first killed his father and thirty of his brothers! He then married his mother and although he spared the progeny that came forth from this union, he ended up killing his mother! This is the way the world is for those who worship it… The person who does not pay attention to the material world will experience peace and comfort for himself, his body and soul, and those around him.
Having an intense attachment to the world will definitely lead to pain, suffering and toils, and as such, a person would, for example, not be able to have a peaceful sleep. There are many people who, when they reach home in the evening from work, see all of the events which took place in the day and all of the transactions which they carried out marching in front of their very eyes.
If they are able to sleep, they do not gain satisfaction from their sleep and if they can not sleep, then it is a night full of grief and sorrow - such people must take sleeping pills just to rest however still, their soul is continuously tormented!
