Remember that it is necessary (wajib) to have a positive assumption regarding Allah Almighty. Never should one be despair of His mercy. He is the Almighty who gives to whosoever He wishes and howsoever He wishes. If He wills, He can seize us because of one sin; and if He wills, He can forgive us out of His mercy just because of one good act. To raise the spirits of the sinful, Allah Almighty gives glad tidings in part 24, verse 53 of Surah al-Zumar:

قُلْ یٰعِبَادِیَ الَّذِیْنَ اَسْرَفُوْا عَلٰۤى اَنْفُسِهِمْ لَا تَقْنَطُوْا مِنْ رَّحْمَةِ اللّٰهِؕ-اِنَّ اللّٰهَ یَغْفِرُ الذُّنُوْبَ جَمِیْعًاؕ-اِنَّهٗ هُوَ الْغَفُوْرُ الرَّحِیْمُ(۵۳)

What importance do I have for You to respond to me by saying ‘لَبَّیْک’.’ Allah Almighty said: ‘I like for someone to call out ‘O Lord’ to me and I reply with ‘لَبَّیْک’.’ Prophet Musa عَـلَيْـهِ الـسَّـلَام said: ‘O Lord, is this for every obedient person?’ Allah Almighty replied: ‘Yes. In fact, it is for every sinful person as well.’ Prophet Musa عَـلَيْـهِ الـسَّـلَام said: ‘[This is] for the obedient because of his obedience. Why is there this mercy for the sinful?’ In response, it was said: ‘O Musa, If I reward the one who does good in return for his good, and I do not do good to the
