In defining the righteous, sameness of behaviour in prosperity and adversity forms a serious consideration; the behaviour pattern may not change in spending—in Quranic idiom, the charity, as laid down in the Holy Verse:
''Those who spend (freely), whether in prosperity or in adversity; who restrain anger, and pardon (all) men: for Allah loves those who do good—(4: 134)
Material wealth may not be grasped holistically for personal benefit, but a reasonable part of it has to be shared with those in need, as per the norms laid down. While it may be easy to part with a part of material wealth in prosperity, in adversity too, it may not be taken to be burden, for the righteous is one, who exhibits sameness of behaviour in spending in prosperity and adversity.
The adverse situation into which a righteous person may find himself is defined in the Holy Verse that follows:
''And those who, having done something to be ashamed of, or wronged their own souls, earnestly bring Allah to mind, and ask for forgiveness for their sins,—and who can forgive sins except Allah?—-and are never obstinate in persisting knowingly in (the wrong) they have done (4: 135)
The righteous on finding himself in sin or error may not whine or despair but ask for Allah (SwT)'s forgiveness. Sincerity demands making amends and abandoning the wrong by making the needed correction.
In doctrine of personal responsibility, committing a sin or getting into an error may not be attributed to blind fate or an angry God lying in wait for revenge or injury to mankind. The righteous need to own the error and get on a corrective course by seeking Allah (SwT)'s forgiveness. And, he may not shirk his responsibility in spending in adverse conditions.
