The following is mentioned in the book Zaydiyya: Qirâ`at fîl-Mashru'u wa Bahth al-Makûnât by ‘Abdullah bin Muhammad al-Hamîd ad-dîn:
"The Jârûdiya is attributed to Abu Jârûd (d. 150 or 160 AH)…Regarding the Suleimâniyya, they are attributed to Suleimân bin Jarîr....”
The book goes on to say that there are contradictions regarding some of the origins, beliefs, and attributions of these groups. Therefore, one cannot say exactly what these groups believe and what their supposed founders actually believed and taught. As an example, it says:
“The Batriyya are attributed to Suleimân bin Jarîr upon one opinion. Others attribute another opinion to him. Regarding the Suleimâniyya, they are attributed to Suleimân bin Jarîr. The Sâlihiyya and the Batriyya are numbered together as one sect. It poses the following problems attributing to them from these perspectives. If the Batriya are attributed to Suleimân bin Jarîr, this would make them and the Suleimâniyya attributed to the same person!”
Regarding the Jârûdiyya, it says:
“Whatever the case, because of the hostility against the Jârûdiyya, one cannot find any traces of them after the 2nd century. One can almost not find anyone who attributes themselves to them. Similarly, after the 2nd century, one cannot find amongst the Zaydis anyone who attributes themselves to this group or say anything similar to what they said.”
So, one cannot say with surety what they said or believed. Similarly, because of the propaganda against and contradictory information about the Houthis, one cannot say what they say, do, or believe.
