Always spend our time in something that benefits us. Don’t waste time in something that doesn’t benefit to use in this world of in the hereafter.
Allah ﷻ says,
وَلَا تَقْفُ مَا لَيْسَ لَكَ بِهِ عِلْمٌ ۚ إِنَّ السَّمْعَ وَالْبَصَرَ وَالْفُؤَادَ كُلُّ أُولَٰئِكَ كَانَ عَنْهُ مَسْئُولًا
❝And do not pursue that of which you have no knowledge. Indeed, the hearing, the sight and the heart – about all those [one] will be questioned.❞[al-Isra’ 17:36]
The one who is sincere to himself should ask and seek to understand what he needs to know with regard to his religion, and what will lead to self-improvement.
