My worshippers who listen to saying and choose with deliberation the fairest course to follow. These are they who have been guided by Allah, and it is these who are endowed with intellects. Does he who is certain of truth of your mission, Muhammad(pbuh),and who knows that all that has been revealed to you from Allah is the truth guiding to all truth ,compare with him who is blind? Indeed ,those who believe in Allah are people of Insight--those who are imbued with intellects by which they perceive, know and judge. ALQURAN.39:18 and 13:19
