Man is Impatient Allah informs about man and his inclination to corrupt his behavior.

Allah says,

إِنَّ الإِنسَـنَ خُلِقَ هَلُوعاً

إِذَا مَسَّهُ الشَّرُّ‌ جَزُوعًا وَإِذَا مَسَّهُ الْخَيْرُ‌ مَنُوعًا (very upset when touched by evil, and very niggard when visited by good (fortune)... 70:20-21). This verse describes the fickle nature of man. When bad things happen to him he becomes desperate and upset, and loses patience. When good things come to him, such as wealth and comfort, he becomes begrudging and miserly in spending his wealth for good causes. 'Impatience', in this context, signifies 'that which is outside the limits of Shari` ah'. 'Niggard', in this context, signifies 'failing to fulfill pecuniary obligations imposed by the Shari'ah' as explained previously. The verses that follow make an exception of the righteous believers to the characteristics of the general body of human beings. This exception starts from إِلَّا الْمُصَلِّينَ (except the performers of salah...70:22) and ends at عَلَىٰ صَلَاتِهِمْ دَائِمُونَ (regular in their salah.... 70:23)

The first exception is expressed with the words 'the performers of salah' [ 22]. Obviously, it means the believers, but referring to them as 'performers of salah' indicates that 'salah' is the greatest sign and the essential characteristic of a believer. In fact, the only people worthy of the name 'believers' are 'the performers of salah'. The following verses describe the qualities of the performers of salah.
