From the Science of Imam Ali part6
If we return to Imams sayings relating the scientific intellect and spirit that he had personally, we will find additional confirmation to that of the dignified Messenger concerning the science in the right of Imam Ali. Imam (peace be upon him) has used the word (Isaluni) means (ask me) frequently in his sermons and talks that has a clear indication of Imams potential in the science, the knowledge and the readiness of answers of what in the mind of people is, and beyond that. For instance, he said ((Ask me before you miss me, because I am certainly acquainted with paths of the sky more than the paths of earth)). And also ((ask me before you miss me; Who split the grain and create the aura if you ask me about which verse revealed in night or it came down in midday))
