in Allah, to give for Allah’s sake, and to withhold for Allah’s sake. This can only be achieved by following the Messenger of Allah, whose command is Allah’s command, whose prohibition is Allah’s prohibition, enmity toward whom is enmity toward Allah, obedience to whom is obedience to Allah, and disobedience to whom is disobedience to Allah.
A person ruled by personal desire is blinded and deafened by it. He neither keeps in mind nor seeks what Allah and His Messenger require in the matter. He is not pleased because Allah and His Messenger are pleased, nor is he angered because Allah and His Messenger are angered. Rather, he is pleased when something accords with his personal desire and angered when something offends it.
At the same time, he entertains a religious misconception: he believes that the cause for which he is pleased and angered is the Sunnah(1), the truth, and the religion. Even assuming that what he upholds is the unalloyed truth—the religion of Islam—if his aim is not that religion should be entirely for Allah and that Allah’s word should be supreme, but rather to defend himself and his faction, or to show off so that he himself will be exalted and praised, or if he acts merely out of courage and natural temperament or for some worldly end, then his action is not for Allah, and he is not striving in the cause of Allah. What, then, if the one claiming to uphold the truth and the Sunnah is no different from his counterpart: he has both truth and falsehood, Sunnah and innovation, while his opponent likewise has both truth and falsehood, Sunnah and innovation?
This is the condition of those who differ, divide their religion, and become sects, some declaring others disbelievers and some declaring others wicked. Allah Most High therefore said concerning them:
“Those who were given the Scripture did not become divided until after the clear proof had come to them. They were commanded only to worship Allah, devoting religion sincerely to Him as people of pure faith, to establish prayer, and to give the prescribed alms. That is the upright religion.”
[Surah al-Bayyinah: 4–5]
And Allah Most High said:
“Humanity was once one community.”
[Surah al-Baqarah: 213]
