Imam Sadiq (peace be upon him): When the Messenger of Allah (peace be upon him and his family) manifested miracles to the Jewish people and to a group of the hypocrites, but they met that truth with disbelief and did not believe, Allah informed [us] about them that He had set a seal upon their hearts and their hearing, a seal that serves as a sign for His angels brought near [to Him], who read what is recorded of the accounts of these deniers in the Preserved Tablet (al-Lawh al-Mahfuz), where their states are mentioned. So when they [the angels] look at their states, their hearts, their hearing, and their sight, and witness there the seal of Allah upon them, the angels' recognition of Allah and certainty of His knowledge of what will happen before it happens increases. And when the angels see these people, sealed upon their hearts and their other faculties just as they had read in the Preserved Tablet, and observe in their hearts, their hearing, and their sight the very things they had read, their faith and certainty in Allah's knowledge of the unseen increases all the more.
