Al-A'raf 7:101 تلك القرى نقص عليك من انبايها ولقد جاءتهم رسلهم بالبينات فما كانوا ليومنوا بما كذبوا من قبل كذالك يطبع الله على قلوب الكافرين ١٠١

Those were the towns whose story We relate unto you (O Muhammad صلى الله عليه وسلم). And there came indeed to them their Messengers with clear proofs, but they were not such as to believe in that which they had rejected before. Thus Allâh does seal up the hearts of the disbelievers (from every kind of religious guidance).
