Muʿjam al-Aḥādīth al-Muʿtabara, Fitting Response Appropriate to the Understanding of the Questioner and the Addressee – Ḥadīth #3
–> The Murjia are an early grouping which held the opinion that judgement should be left to Allāh as per someones Iman. Even someone who commits a major sin remains a believer, because faith is independent of deeds and requires but acknowledgment of the Shahada. “The one who commits Zina near the Ka’ba has equal faith to angel Gabriel near the Arsh”.
–> The Khawarij held the opposite position whereby they excommunicated anyone they felt was not living up to the high standards they expected a Muslim to demonstrate, this Takfir would make such a person’s blood permissible to be shed.
The Qadariyya believed in absolute free-will, a reaction against the Jabriyya (pre-destinarians), they held that God had no role in human actions, and humans had full control over their actions and destiny.
al-Moḥsini says: the narration concerns someone who is in doubt whether a Hadith is true or false, but if one is certain of a Hadith’s falsity then it is permitted for him to reject it, and there is no doubt that people lied and fabricated things and attributed them to the prophet, and the Aimma, even Allāh the Exalted – for instance in some reports which are called the Qudsiyya which the Sufis and their likes have forged.
In conclusion: if a narration is not established to be originating from them then it is not permitted to depend upon it, as the Book and the narrations that are to come and have already come indicate – but one should avoid calling it a lie if one is in doubt as regards its status.
