According to this hadith, it is a quality of a Muslim that he or she is very concerned about acquiring virtues and doing good, and never tires of struggling for and living by virtuous deeds. This is because “a believer sees his sins as if he were sitting under a mountain which, he is afraid, may fall on him; whereas the wicked person considers his sins as flies passing over his nose and he just drives them away like this. Abu Shihab (the sub-narrator of this statement of Abdullah ibn Masud’s) moved his hand over his nose in illustration.” [Sahih Bukhari]
High achieving students never stop studying because they never feel satisfied that what they know is sufficient. They don’t limit themselves to the bare minimum amount of knowledge needed to pass. One who does so is in danger of failing. Even when they are well prepared they feel that they could know more, or that they might make a mistake which they would have to compensate for with something else. Another reason that high achieving students keep on studying is because of their love for learning.
Similar is the case of a Muslim with good deeds. They love to please Allah (Subhana wa ta’ala) and enter His Jannah. Additionally, they are afraid that what they have prepared of good deeds may not be sufficient so they keep doing what is pleasing to Allah (Subhana wa ta’ala). A borderline pass is not what they aim for, because one could easily make a mistake and end up failing. They aim for a high ‘A’. They do not underestimate the enormity of the sins that they commit and see their sins as a huge mountain looming over them. Thus, they are always trying to compensate for their shortcomings. In this struggle a Muslim reaches the end of his or her life. Such is the successful person for he achieves Jannah.
