Translation of the verse 110 from Surah Ta-Ha : Number of verses 135 - - page 319 - Part 16.
He (Allah) knows what happens to them (His creatures) in this world, and what will happen to them (in the Hereafter), and they will never compass anything of His Knowledge.
Allah knows what is [presently] before them and what will be after them, but they do not encompass it in knowledge.
(20:110) -He is fully aware of all that is before the people and of all that is behind them but others do not have full knowledge of it. *86
*86) Here the reasons for the restrictions on intercession have been stated. On the one hand, no angel, no prophet, no saint, nor anyone else knows, nor can know, the full details about the records of others. On the other hand, Allah has full knowledge of all the deeds and misdeeds of everyone and He knows who deserves pardon or punishment, and how much. If, therefore, there had been full freedom for intercession the whole purpose of the creation of man would have become meaningless. According to this verse, the door against intercession has not been entirely closed. The righteous people will be allowed to show their sympathy for other human beings as they did in the world, but they will have to get permission for this beforehand and even then make only a right sort of recommendation .
