It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both); he said: The Messenger of Allah (peace and blessings be upon him) said: "May Allah Almighty have mercy on Musa (peace be upon him). Seeing with one's own eyes is not like hearing news. His Lord informed him that his people had fallen into trial after he left them, and he did not throw down the Tablets (at that time); but when he saw them for himself, he threw down the Tablets (in the intensity of his emotion)." And the Messenger of Allah (peace and blessings be upon him) said: "May Allah Almighty have mercy on Musa (peace be upon him). Had he not been hasty, more events from his story would have been related." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.
