Those who believed and did righteous deeds have 'Thooba' and the best return.
While the Fujjar-inhabitants of Hades-have the filthy Zaqqum tree as told in verses 37: 62-67, the believers will have the 'Thooba' tree in Paradise. Lord explained through His Messenger: "Thooba is a tree in Paradise, its shade spreads up to 100 light-years. The rivers of honey, milk, and pure water mentioned in verse 47: 15 in Paradise are flowing beneath it. The inhabitants of Paradise will have dresses from the chaff of this tree".
One can become a believer only with Adhikr-the Permission of Lord as explained in verse 10: 100. Indeed, those who believed with Adhikr and propagate It throughout the World, those are the best creatures in the land. They have their reward near their Lord which is the Paradise of eternity beneath which rivers are flowing; they will abide in it forever eternally, Lord has satisfied with them and they are satisfied with Him, that is for the one who fears his Lord as explained in verse 4: 57. See explanation 2: 25; 9: 71-72 and 12: 56-57.
