Ibn Shabrima said" Nobody said while he was on the platform (ask me) except Ali)) .
This phrase and this repetition are a clear indication of the powerful scientific spirit and the strong desire to spread the science and the knowledge among Muslims.
Imam Ali (peace be upon him) realized scientifically the value of the question, because it is the key of the science, so he encourages the asker to more science and knowledge. Therefore, he (peace be upon him) mentioned the question and science in his saying ((Science is treasuries and their sky is the question, so please, Allah mercy upon you. He summarized the matter in four steps: the asker and the teacher, the receiver and sender, and the one loving them))
