Abul Abbas Abdullah ibn Jafar al-Himayri narrated in his “Qurub al-Isnad” book (p61/#193),
« قال رسول الله : عن يمين الله ـ وكلتا يديه يمين ـ عن يمين العرش قوم على وجوههم نور ، لباسهم من نور ، على كراسي من نور. فقال له علي : يا رسول الله ، من هؤلاء؟ فقال له : شيعتنا وأنت إمامهم »
Messenger of Allah (sallalahu alaihi wa ala alihi wa sallam) said: From the right hand of Allah – AND HIS BOTH HANDS ARE RIGH – from the right of Arh – group of people, there is a light upon their faces. And their clothes from light, and they are on the chairs from light. Ali said: O messenger of Allah, who are they? He said: Your shias, and you their Imam”
all shi’ites believe that 5 infallibles were made from noor of Allah ,hence noor of Allah came to us in human form as per shia beliefs .this is also a form of tajseem ,what do shi’ites say about that?
