Man is Impatient Allah informs about man and his inclination to corrupt his behavior.
Allah says,
إِنَّ الإِنسَـنَ خُلِقَ هَلُوعاً
(Verily, man was created very impatient;) Then, Allah explains this statement by saying,
إِذَا مَسَّهُ الشَّرُّ جَزُوعاً
(Apprehensive when evil touches him;) meaning, whenever any harm touches him he is frightful, worried and completely taken back due to the severity of his terror and his despair that he will receive any good after it.
وَإِذَا مَسَّهُ الْخَيْرُ مَنُوعاً
(And suppressive when good touches him.) meaning, if he attains any blessing from Allah, he is stingy with it, not sharing it with others. He will withhold the right of Allah with that blessing. Imam Ahmad said that Abu `Abdur-Rahman informed them that Musa bin `Ali bin Rabah told them that he heard his father narrating from `Abdul-`Aziz bin Marwan bin Al-Hakim that he heard Abu Hurayrah saying, "The Messenger of Allah ﷺ said,
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 scenes of Doomsday cannot either be revealed in reality or truly described in the present world. However, in the Quran, these have been allegorically conveyed by allusions and examples, so that man should have a brief idea of their significance. When Doomsday arrives, it will be so terrible that man will forget this relations and the interests to which he gives the utmost importance today and for which he ignores the Truth.
