(Ar-Ra'd) 13 : 26
اللَّهُ يَبْسُطُ الرِّزْقَ لِمَنْ يَشَاءُ وَيَقْدِرُ ۚ وَفَرِحُوا بِالْحَيَاةِ الدُّنْيَا وَمَا الْحَيَاةُ الدُّنْيَا فِي الْآخِرَةِ إِلَّا مَتَاعٌ
Lord Allah increases sustenance for whom He Wishes and He limits the provision for whom He Wishes. And they rejoice in the worldly life, while the worldly life is nothing except limited sustenance comparing with the Hereafter.
Lord deputed mankind on earth to test them with whatever He has provided to them as explained in verses 5: 48 and 6: 165. By codifying Adhikr-the Mercy and Bounty-through the Three-Time-Knower mentioned in verse 25: 59, Lord has become the Impartial. Adhikr is the prosperity, there is no poverty after It, and there is no prosperity without It as explained in verse 2: 272. So, the odd believer will lead a life testifying Adhikr as explained in verses 7: 205-206. See explanation 2: 174-176; 3: 196-197 and 9: 58-59.
