A summary of the concepts of Ahl al-Sunnah. The injustice of some callers (to Islam) against others. Arising from division and disagreement. The most infuriating thing for Satan, is to see affection, love, and unity among the righteous callers within this Ummah. And the most joyful thing for him is to sow division and enmity between them. This is because he knows that unity is a cause of victory and success in this world and the Hereafter, while division leads to failure and loss of momentum. Similarly, in an atmosphere of division and disagreement, oppression spreads. Among the manifestations of this injustice occurring today among Muslims are the following: Firstly, backbiting and tale-bearing stemming from envy and malice, and harboring ill suspicions of callers (to Islam) and scrutinizing their faults. Secondly, the matter may go beyond backbiting and envy to attempting to inflict harm and damage upon some reformers, and spreading false slanders that result in harm to the body, honor, or wealth. Thirdly, neglecting the rights of scholars, forgetting their sacrifices, efforts, and struggles, merely because of one slip or several slips found against them. This is a form of injustice, lack of fairness, and inequity. Fourthly, rejoicing when scholars and reformers fall into errors and transgressions, and feeling saddened and disheartened when they attain the truth, and gloating over them if misfortune and harm befall them. Fifthly, lack of clarity and lack of sincerity among scholars, and dealing with ambiguous, convoluted methods, which may involve lies, treachery, and betrayal. All of this is from injustice and the erasure of blessings. Sixthly, remaining silent about the injustice and aggression that befalls some callers (to Islam), and refraining from supporting them when able, and sitting with those who speak ill of them and fabricate lies against them, attributing faults to them without denouncing them, or distancing oneself from them when unable to denounce. Seventhly, Among the injustices occurring between some callers (to Islam) is unfairness and aggression in their responses to one another, whether in dialogue, debates, or written form. And these responses are often governed by personal desires, especially if they occur in the presence of a group of people. Among the manifestations of this aggression: accusing intentions and motives, rejecting the truth that becomes apparent from the opponent's tongue, obligating the opponent to consequences of their words that they themselves do not adhere to, and leveling accusations against the opponent for which there is no evidence, and being fanatically attached to certain opinions even if they are false.
