Concise Quran Commentary
Their reward with their Lord (may He be glorified) is gardens under the trees and palaces of which rivers flow, and wherein they shall remain forever. Allah is pleased with them because of them bringing faith in Him and obeying Him, and they are also pleased with Him because of Him giving them His mercy. This mercy can be acquired by the one who fears his Lord, and so fulfils His command and refrains from the thing He has not allowed.
