In the Qur'aan, Allaah سبحانه و تعالى has described mankind as apt to committing a great deal of dhulm to itself and others. For example, Allaah سبحانه و تعالى has said,
"If you count the blessings of Allaah, never will you be able to count them. Verily, man is indeed an extreme wrongdoer, an extreme ingrate." (Soorah Ibraaheem, 14:34)
This gives the impression that it is easy for man, given his nature, to commit dhulm and he is prone to committing dhulm often. When a Muslim realises this fact and he also realises how dangerous dhulm is to his religion and well-being, he will seek the means that will help him avoid dhulm as much as possible.
Sultaan mentions the following means that may help a person in preventing himself from committing dhulm.
First, the person must develop taqwa within himself. Taqwa will help the person remain away from dhulm as dhulm is an act that is very displeasing to Allaah and He has forbidden it. 
Second, the person should try to develop humility in himself. Sultaan mentions this point because he says that humility is the opposite of pride and arrogance, which are two of the factors that lead many people to commit dhulm. 
Third, the person should try to free himself from any feeling of hasad (envy) because hasad is also a major cause behind much dhulm.
Fourth, the person should read about the great reward for being just and righteous (the opposite of dhulm) and how pleasing it is to Allaah سبحانه و تعالى. In other words, he should read those verses and ahaadeeth, some of which were mentioned above, that will incite him to take those praiseworthy characteristics.
Fifth, he should turn to Allaah سبحانه و تعالى and
Sixth, the person should think about and take seriously the evil results of committing dhulm. He should realise that no real success or prosperity will ever come to those who are dhaalimeen (wrongdoers). He should reflect upon Allaah's words,
"Verily, the people who commit dhulm will never be successful." (Soorah al-An'aam, 6:21)
He should reflect upon the fact that committing dhulm may keep one from getting guided by Allaah سبحانه و تعالى. In his prayers, while reciting Soorah al-Faatiha, he may ask Allaah سبحانه و تعالى to guide him to the straight path but he may not be so guided because of his acts of dhulm which are a barrier to his
"Allaah does not guide the wrongdoing folk (adh-dhaalimeen)." (Soorah at-Tawbah, 9:19)
He should also consider the punishment for the wrongdoers as was mentioned in the verses and ahaadeeth quoted earlier. He should recall that the punishment for the wrongdoers is not just in the next life but, in one way or another, they will receive some punishment in this life. Allaah سبحانه و تعالى says,
"And verily, for those who do wrong (dhalamoo), there is another punishment (that is, the torment in this world and in their graves) before this, but most of them know not." (Soorah at-Toor, 52:47)
In the Hereafter, he will have no friend or supporter to help him, as Allaah سبحانه و تعالى states,
"Our Lord! Verily, whom You admit to the Fire, indeed, You have disgraced him, and never will the Dhaalimeen (polytheists and wrong-doers) find any helpers." (Soorah Aali 'Imraan, 3:192)
"And warn them (O Muhammad صلى الله عليه وسلم) of the Day that is drawing near (i.e. the Day of Resurrection), when the hearts will be choking the throats, and they can neither return them (hearts) to their chests nor can they throw them out. There will be no friend, nor an intercessor for the Dhaalimeen (polytheists and wrong-doers, etc.), who could be given heed to." (Soorah Ghaafir, 40:18)
