7. Muhammad ibn al-Hasan ibn Ahmad ibn al-Walid said: Muhammad ibn al-Hasan alSaffar said: Ahmad ibn Muhammad ibn `Isa said, on the authority of al-Hasan ibn `Ali ibn Fuddal, on the authority of Tha`labah ibn Maymun, on the authority of al-Hasan ibn al-Sayqal, on the authority of Muhammad ibn Muslim, that Abu Ja`far al-Baqir said: Discuss about anything but the Throne. And discuss about anything other than what is above the Throne. A group once conversed about the Essence of Allah, the Mighty and High. They became so bewildered that when someone called one of them from in front, he would answer from behind, when someone called on of them from behind, they would answer from in front (meaning he lost his sense).
