对于那些在没有相应知识的情况下就对安拉的尊名、属性和行为发表意见的人，这是一种大罪。以与安拉自己所描述的、或先知ﷺ所描述的相悖的方式来形容安拉，也是大罪。这对于那位拥有创造与命令的、至完美属性的主而言，是最为败坏的行为。如果这种行为是出于明知而为，那便是一种顽固，在安拉看来，它甚至比以物配主更为邪恶。一个仍承认主的属性的多神教徒，比否认主的完美属性的人，罪过要轻！否认主的属性，正是无法治愈的顽疾。法老作为这类多神教徒的首领，在穆萨（摩西）说他的主在诸天之上时予以拒绝，于是他回应说："哈曼啊！你为我建一座高塔，好让我得以抵达那些途径，即诸天的途径，我好去看看穆萨的神。但我确信他是个说谎者。"（《古兰经》40:36-37）谢赫艾布·哈桑·艾什尔里以这节经文作为论据，反驳所有否认安拉自身属性的人。 偏离正道的革新是最大的罪恶之一，比其他大罪更受易卜劣厮（撒旦）的喜爱。一位前贤说："革新比违抗安拉的行为更受易卜劣厮喜爱，因为人可以为违抗的行为悔罪，却很难为革新悔罪。" 易卜劣厮说："我用罪恶去迷惑亚当的子孙，他们却用求安拉饶恕、并作证除安拉之外没有应受崇拜的主来对付我。我见此情形，便在他们中间制造派别（和异端倾向）；于是他们犯罪而不悔改，因为他们以为自己在用行为行善！" 罪人只伤害自己；而革新者则既伤害自己，也伤害他人。 创新者的 fitnah（考验、试炼、灾难）触及宗教的根基；而罪人的 fitnah 则在于他必须与自己的私欲抗争。创新者会把人们从正道上赶走，罪人则不会这样做。创新者剥夺了人们通往后世的正道，而罪人则因自己的罪过而行进缓慢。

It is a great evil to give one's opinion regarding the Names, Attributes and Actions of Allah ~ without having any proper knowledge about them. To describe Allah ~ with anything contrary to what He ~ has described Himself, or has been described with by the Prophet ~ is also a great sin. It is the most degenerate thing to do to the Attribute of Perfection of the One Who is the Owner of the Creation and the Command. If such an act is issued out of knowledge, then it is an act of obstinacy, which is even more evil than polytheism in the Sight of Allah. A polytheist who still acknowledges the Attributes of the Lord is less evil than the one who denies the Lord His Attributes of Perfection! The denial of the Attributes of the Lord IS the ailment without a cure. Pharaoh, the leader of such polytheists, rejected the statement of Musa (Moses) ~I, when he said that his Lord was above the heavens; so he responded, saying: ( 0 Haman! Build me a tower that I may arrive at the ways; the ways of the heavens, and I may look upon the God of Musa. But verily, I think he is a liar.) 3 Shaikh Abu Al- Hasan Al-Ash'ari used this Verse as argumentative evidence against all those who deny Allah His Own Attributes. Deviating innovation is one of the greatest sins; and is more preferred by Iblis (Satan) than other major sins. One of the past scholars said: "An innovation is more beloved by Iblis than an act of disobedience to Allah; because one can repent from a disobedient act, but can hardly do so from an innovation." lblis said: "I have exhausted the Children of Adam with sins, and they have exhausted me by seeking forgiveness from Allah and testifying that there is no god worthy of worship but Allah, Alone. On seeing this, I established among them sects (and heretic tendencies); so they commit sins and do not repent from them, because they think that they are acquiring good by their deeds!" A sinner harms only himself; whereas an innovator harms himself as well as upon other people. The fitnah (test, trial, tribulation) of an innovator affects the basis of religion; whereas the fitnah of a sinner is in having to cope his own desires. An innovator drives people away from the Right Path, whereas a sinner does not do so. An innovator denies people the right way to the Hereafter, whilst a sinner is slowed down because of his sins.
