ترجمة الآية 101 من سورة Al-A‘raf - English - سورة الأعراف : عدد الآيات 206 - - الصفحة 163 - الجزء 9.
Those were the towns whose story We relate unto you (O Muhammad SAW). 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 Allah does seal up the hearts of the disbelievers (from each and every kind of religious guidance).
Those cities - We relate to you, [O Muhammad], some of their news. And certainly did their messengers come to them with clear proofs, but they were not to believe in that which they had denied before. Thus does Allah seal over the hearts of the disbelievers.
(7:101) To those [earlier] communities - some of whose stories We relate to you - there had indeed come Messengers with clear proofs, but they would not believe what they had once rejected as false. Thus it is that Allah seals the hearts of those who deny the truth. *81
*81). The purpose behind the 'sealing of hearts' mentioned in the preceding verse is also explained in the present verse. It is clear from the two verses that the 'sealing of hearts' means that man's capacity to hear and understand the truth is seriously, impaired because of the operation of natural, psychological laws. Because of these laws, once a person turns away from the truth because of his irrational prejudices and the dominance of lust, he becomes enmeshed in his own obstinacy and adamance. With the passage of time this adamance is compounded to such an extent that despite all rational and empirical evidence in support of the truth, he continues to reject it.
