3844 The true test of progress in spiritual life is to be measured by other things than material wealth and influence. What we have to ask ourselves is: are we the least bit nearer to Allah?. 3845 Cf.
30:39. All worldly goods are but a shadow that will pass away. Its intrinsic and eternal value is small. But those who work righteousness in Faith are on the true path of self-development. The rewards they will get will be intimately more than their merits entitle them to. For they will partake of the boundless Bounties of Allah. 3846 Their happiness will not only be great in quantity ("multiplied"), but it will be of a specially sublime quality ("dwellings on high"), and it will endure without any chance of its loss or diminution ("secure they reside").
