The verse says...
The verse says: “No toil there shall afflict them in it, nor shall they be ever cast out of it.” Attention: The Arabic term /qill/ mentioned in verse 47 signifies secret infiltration. Therefore, evil characteristics set in their roots secretly in human beings. The Qur’anic terms /surur/ amd /sarir/ are derived from the word /surūr/ which means ‘throne’. One concludes that accession to the throne is pleasant and causes one’s rejoicing.
“And that My chastisement is the painful chastisement.” Now, it may be possible that some sinners and deviant individuals sink in their own depression, saying: “We wish we could also reap parts of such blessings.” It is at this moment that Allah, the Compassionate, the Merciful, opens up the gateways of Paradise to them, but with some conditions.
“When they entered upon him and said: ‘Peace’, he said: ‘Verily we are scared of you!’” From this verse on, the Qur’an discusses some instructive parts of the history of great prophets and the disobedient nations as clear examples of the devotee servants and the followers of Satan. It begins with the story of ‘Ibrahim’s guests, saying: “And inform them of the guests of Abraham.” These uninvited guests were the same angels who anonymously called on ‘Ibrahim first, and said /salam/ (peace) to him.
