It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Information is not like witnessing. When Allah Almighty informed Musa (peace be upon him) that his people had done such and such with the calf, he did not throw down the tablets. But when he saw what his people had done, then he cast down the tablets and they broke."
