Moses and Al-Khadir
Allah said ( interpretation of the meaning ) : { And they found a servant from among Our servants to whom we had given mercy from us and had taught him from Us a [certain] knowledge. Moses said to him, "May I follow you on [the condition] that you teach me from what you have been taught of sound judgement?" He said, "Indeed, with me you will never be able to have patience. And how can you have patience for what you do not encompass in knowledge?" [Moses] said, "You will find me, if Allah wills, patient, and I will not disobey you in [any] order." } Quran ( 18 : 65 - 69 )
We learn from this situation to stick to humbleness while seeking the knowledge. As well to be keen on accompanying the the righteous people. Indeed over every possessor of knowledge is one [more] knowing.
