The Meaning of Injustice in the Statement: (Those who believe and do not mix their faith with injustice)

Question:
May Allah reward you with good. This verse is the statement of Allah the Exalted: How do we reconcile the security mentioned in the noble verse with the fear mentioned in the hadith? And what is the fear that a person should have toward Allah (Glorified and Exalted is He)? May Allah reward you with good. As for the statement of Allah the Exalted, "Those who believe and do not mix their faith with injustice, those are..." , the intended meaning is that the injustice referred to here is shirk (associating partners with Allah).

Answer:
Because when this [verse] was revealed, its matter was difficult for the Companions of the Messenger of Allah (peace and blessings be upon him), and they said, "O Messenger of Allah, which of us has not wronged himself?" They thought that the injustice referred to was sins. So the Prophet (peace and blessings be upon him) said to them, "It is not what you mean, but rather it is shirk (associating partners with Allah). Have you not heard the statement of the righteous servant: ?" So the statement of Allah the Exalted, Indeed, the polytheist has no security in this world or in the Hereafter. As for the believer, the believer who is a monotheist and sincere to Allah (Mighty and Majestic), who avoids shirk, whether major or minor, he has security in this world and the Hereafter. If his faith is complete and he is safe from sins and disobedience, then he has complete security with no fear. And if he has some sins that are less than shirk, then he is safe from eternal abode in the Fire; he is safe from eternal abode in the Fire. If he enters it, he must surely come out of it and enter Paradise. So he has security, but it is incomplete due to sins and disobedience, and he is threatened with the warning, but his ultimate end is Paradise. So he has absolute security, but not absolute security. Absolute security is complete security. As for absolute security, it is security accompanied by some fear, and he fears punishment, but he has security. As for the disbeliever and the polytheist, may Allah protect us from that, they have no security at all. Rather, for them is pure fear, may Allah protect us from that, in this world and the Hereafter. Yes.
