'I told Abu 'Abdillah [i.e. Imam al-Sadiq] (AS): 'Verily they are saying things [about you]!' He asked, 'What are they saying?' to which I replied, '[They are saying], 'He knows the number of drops of rain, the number of stars and the leaves on the trees, and the weight of all that is in the sea, and the number of grains of sand.' So he raised his hands to the sky, saying, 'Glory be to Allah, Glory be to Allah. No, by Allah, no one knows this except Allah.'
