opinion of Muslims, this heart will become a means of an increase in our good deeds, and if we have a bad opinion of Muslims without a reason, then remember, there is fear of being taken to task for this! Hence, it is stated in part 15, Surah Bani Israeel, verse 36:

اِنَّ السَّمْعَ وَ الْبَصَرَ وَ الْفُؤَادَ كُلُّ اُولٰٓىٕكَ كَانَ عَنْهُ مَسْـٴُـوْلًا (۳۶)

Indeed, the ear, the eye, and the heart; all of these are going to be questioned.

[Kanz-ul-Iman (translation of Quran)] (Part 15, Surah Bani Isra’eel, Verse 36)

A’la Hadrat Imam Ahmad Raza Khan رَحْمَةُ الـلّٰـهِ عَلَيْه states: The heart which has the best interests of the entire body, such that if one body part feels pain the heart also feels it, but our state is such that it has become sick due to repeatedly sinning, then how will this heart wish well for us? Only Allah Almighty knows what will become of us.

Dear Islamic brothers! Remember! And remember well! After spending a few days in this temporary world, we will be lowered into a dark grave and we do not know how long we will spend in the loneliness of the grave, and then we will be presented in the court of Our Creator and Lord on the Day of Judgement, where we will be shown every action from our book of deeds, just as it is stated in the Quran, in part 30, Surah Zil-Zaal, verses 6, 7 & 8:

یَوْمَىٕذٍ یَّصْدُرُ النَّاسُ اَشْتَاتًا ﳔ لِّیُرَوْا اَعْمَالَهُمْؕ(۶) فَمَنْ یَّعْمَلْ مِثْقَالَ ذَرَّةٍ خَیْرًا یَّرَهٗؕ(۷) وَ مَنْ یَّعْمَلْ مِثْقَالَ ذَرَّةٍ شَرًّا یَّرَهٗ۠(۸)

On that Day, people will return towards their Lord, in different paths, in order to be shown their deeds. So, whosoever does a good deed equal to the weight of an atom, (he) shall see it. And whoever does an evil deed equal to the weight of an atom, (he) shall see it.

[Kanz-ul-Iman (translation of Quran)] (Part 30, Surah Al-Zilzaal, Verses 6-8)
