(Al-Insan) 76 : 7
يُوفُونَ بِالنَّذْرِ وَيَخَافُونَ يَوْمًا كَانَ شَرُّهُ مُسْتَطِيرًا
They are fulfilling their vows and fearing a Day encompassed with troubles.
The virtuous keep up their words and promises especially their covenant made in the Paradise with Allah. The virtuous shall lead a life here by fearing the Day of Judgment. Read together the verses 45:28-32; 70: 4 and 73: 17 in Adhikr- True Book.
