Good and Bad Deeds
فَمَن يَعْمَلْ مِثْقَالَ ذَرَّةٍ خَيْرًۭا يَرَهُۥ
So whoever does an atom’s weight of good will see it. [99:7]
وَمَن يَعْمَلْ مِثْقَالَ ذَرَّةٍۢ شَرًّۭا يَرَهُۥ
And whoever does an atom’s weight of evil will see it. [99:8]
These two ayats have a simple meaning behind them. All the good you do in your life, it can be the smallest good deed or the largest, won't go unnoticed by Allah. And all the bad you do in your life, it can be a minor sin or a major sin, won't go unnoticed by Allah. All good and bad deeds won't be missed in our record books. We will be asked for all things that we did in this Dunya.
وَٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّـٰلِحَـٰتِ لَنُكَفِّرَنَّ عَنْهُمْ سَيِّـَٔاتِهِمْ وَلَنَجْزِيَنَّهُمْ أَحْسَنَ ٱلَّذِى كَانُوا۟ يَعْمَلُونَ
Those who believe and do good deeds, We shall cleanse them of their evil deeds and reward them according to the best of their deeds. [29:7]
Evil will be punished to the extent that the evil has been committed, but the good deeds will be rewarded much more generously than what they will actually deserve. That is how generous Allah (SWT) is.
I want to remind myself first and then everyone else that even by picking up the tiniest piece of trash from our beautiful Earth, you will be rewarded for it. SubhanAllah. Or even smiling at someone is a good action even if you're having a bad day. Holding the door for someone, making sure others are okay by checking on them, making dua for someone, etc. Even the good actions behind closed doors will certainly be rewarded, it's important to remember that.
May Allah except all our good deeds and forgive all our bad deeds!
