Reminder: A Beautiful Observation by Imaam Ibnul Qayyim Regarding the Reason behind the Misguidance of Some of Those Who Came After the Sahaabah
Imaam Ibnul Qayyim (rahimahullaah) said:
As for those who came after the Sahaabah (i.e. us), amongst them is that one who was brought up in Islaam but knows not what is in opposition to it. Therefore, some of the details of the path of the believers and that of the criminals became confusing to him, for indeed confusion occurs due to weakness of one’s knowledge regarding both paths or one of them, as Umar Ibnul Khattaab (radiyallaahu-anhu) said: ”The ties of Islaam will be demolished one after the other when a people brought up in Islaam know not what Jaahiliyyah (Pre-Islamic Ignorance) is.” This (statement shows) the excellence of Umar’s (radiyallaahu-anhu) knowledge.
And there is that one who is neither acquainted with the path of the criminals nor has it been made clear to him, or he has doubts and thus thinks that some of their ways are from the ways of the believers. This has occurred in this Ummah in many affairs related to Aqeedah, Knowledge and Action, which are from the path of the criminals, the disbelievers and the enemies of the Messengers and were introduced into the path of the believers by those who do not know the (detailed distinction between) the path of believers and the path of the criminals; so they call to (this path of the criminals); excommunicate the one who oppose them and declare lawful that which Allaah and His Messenger made unlawful, just as what has occurred with many of the people of bidah, such as the Jahmiyyah, the Qadariyyah, the Khawaarij, the Rawaafid and their likes – those who initiated an innovation, called to it and excommunicated those who opposed it.
