Qu’ran - The Qu'ran alone is to be followed - Surah Al An’am
Type of Spiritual Experience
This has particular importance, as it implies that what was revealed in the Qu'ran was an authentic message, and the only one of any validity.
Hadith, Arabic Ḥadīth (“News” or “Story”), are second only to the authority of the Qurʾān, the holy book of Islam.
The criticism of Hadith refers to the critique directed towards collections of ahadith. The criticism revolves primarily around the authenticity of hadith reports and whether they are attributable to Muhammad, as well as theological and philosophical grounds as to whether the hadith can provide rulings on legal and religious matters when the Quran has already declared itself "complete", "clear", "fully detailed" and "perfected".
Because of Quranic injunctions to Muslims to follow the instructions of and to imitate the behavior of Muhammad, in Muslim political or religious disputes (especially during the early era of Islam) temptation was strong to fabricate hadith as a "polemical ideological tool" in favor of the fabricator's political/religious position.
This single paragraph makes it clear that the Qu'ran can stand alone. Hadiths are not needed
A description of the experience
Qu’ran- Surah Al An’am translated by Sahih International
6:116 And if you obey most of those upon the earth, they will mislead you from the way of Allah . They follow not except assumption, and they are not but falsifying.
6:118 So eat of that [meat] upon which the name of Allah has been mentioned, if you are believers in His verses.
6:119 ……..And indeed do many lead [others] astray through their [own] inclinations without knowledge. Indeed, your Lord - He is most knowing of the transgressors.
People claiming revelation they did not receive, will be punished
6:93 And who is more unjust than one who invents a lie about Allah or says, "It has been inspired [revealed] to me," while nothing has been inspired [revealed] to him, and one who says, "I will reveal [something] like what Allah revealed." And if you could but see when the wrongdoers are in the overwhelming pangs of death while the angels extend their hands, [saying], "Discharge your souls! Today you will be awarded the punishment of [extreme] humiliation for what you used to say against Allah other than the truth and [that] you were, toward His verses, being arrogant."
