Calling to Islam

And how many a city was stronger than your city [Makkah] which drove you out? We destroyed them; and there was no helper for them. So is he who is on clear evidence from his Lord like him to whom the evil of his work has been made attractive and they follow their [own] desires? Is the description of Paradise, which the righteous are promised, wherein are rivers of water unaltered, rivers of milk the taste of which never changes, rivers of wine delicious to those who drink, and rivers of purified honey, in which they will have from all [kinds of] fruits and forgiveness from their Lord, like [that of] those who abide eternally in the Fire and are given to drink scalding water that will sever their intestines?And among them, [O Muhammad], are those who listen to you, until when they depart from you, they say to those who were given knowledge, "What has he said just now?" Those are the ones of whom Allah has sealed over their hearts and who have followed their [own] desires. Quran  47: 13-16
