And among these polytheists is he who listens to you the Qur'an-O Messenger-, but it does not reach their hearts; because of their following their desires We placed upon their hearts coverings; lest they understand the Qur'an, and We placed in their ears a heaviness and deafness so they do not hear nor perceive anything, and if they see the many verses indicating the truthfulness of Muhammad, peace and blessings of Allah be upon him, they do not believe in them, until when they came to you-O Messenger-after witnessing the verses indicating your truthfulness they dispute with you: those who rejected the verses of Allah say: "This which we hear is not but what the former ones passed down of stories having no reality."
