Translation of the verse 18 from Surah Yunus : Number of verses 109 - - page 210 - Part 11.
And they worship besides Allah things that hurt them not, nor profit them, and they say: "These are our intercessors with Allah." Say: "Do you inform Allah of that which He knows not in the heavens and on the earth?" Glorified and Exalted be He above all that which they associate as partners with Him!
And they worship other than Allah that which neither harms them nor benefits them, and they say, "These are our intercessors with Allah " Say, "Do you inform Allah of something He does not know in the heavens or on the earth?" Exalted is He and high above what they associate with Him
(10:18) They worship, beside Allah, those who can neither harm nor profit them, saying; 'These are our intercessors with Allah.' Tell them (O Muhammad): 'Do you inform Allah of something regarding whose existence in the heavens or on the earth He has no knowledge? *24 Holy is He and He is exalted far above what they associate with Him in His divinity'.
*24). To say that something is not known to God amounts to saying that it does not exist. For, quite obviously, all that exists is known to God. The above verse thus subtly points out the non-existence of any intercessors on behalf of unbelievers insofar as God does not know that there exist any in the heavens, or on the earth who would intercede on behalf of the unbelievers. That being so, who are those intercessors about whose existence and whose power of intercession with God the unbelievers wanted to inform the Prophet (peace be on him)?
