Yunus - 10:18
They serve, besides Allah, things that hurt them not nor profit them, and they say: "These are our intercessors with Allah." Say: "Do ye indeed inform Allah of something He knows not, in the heavens or on earth?- Glory to Him! and far is He above the partners they ascribe (to Him)!"
Yusuf - 12:106
And most of them believe not in Allah without associating (other as partners) with Him!
Al Araf - 7:187-188
They ask you (Prophet Muhammad S.A.W.) about the (final) Hour - when will be its appointed time? Say: "The knowledge thereof is with my Lord (alone): None but He can reveal as to when it will occur. Heavy were its burden through the heavens and the earth. Only, all of a sudden will it come to you." They ask you as if you wert eager in search thereof: Say: "The knowledge thereof is with Allah (alone), but most men know not."
Say: "I have no power over any good or harm to myself except as Allah willeth. If I had knowledge of the unseen, I should have multiplied all good, and no evil should have touched me: I am but a warner, and a bringer of glad tidings to those who have faith."
And Allah Knows Best!!
