MERCY AND FORGIVENESS FOR THE ONE WHO REPENTS
When Mansur bin 'Ammar رحمة لله علیھ once entered the court of Abdul-Malik bin Marwaan, the latter said, "O Mansur, I have a question for you, and I will give you respite for an entire year to answer it: Who is the wisest of people, and who is the most ignorant of people?"
Al-Mansurرحمة لله علیھ left the castle and spent some time in contemplation in a nearby courtyard. Then the answer came to him, and so he quickly hurried back to Abdul-Malik. "O Mansur, why have you returned?" asked Abdul Malik.
"The wisest of the people, O Leader of the Believers, is the doer of good deeds who fears not having his deeds accepted," said Mansurرحمة لله علیھ." "And the most ignorant of people is he who does good deeds and feels safe in that his deeds will be accepted." Upon hearing these words, Abdul-Malik began to cry until his garment became soaked in tears. He then said, “You have done well, O Mansur. Now, recite a part of the Quran to me, for the Quran is a cure for what is in the breasts of men."
Mansurرحمة لله علیھ then recited this verse:
یَوۡمَ تَجِدُ کُلُّ نَفۡسٍ مَّا عَمِلَتۡ مِنۡ خَیۡرٍ مُّحۡضَرًا ۚۖۛ وَّ مَا عَمِلَتۡ مِنۡ سُوۡٓءٍ ۚۛ تَوَدُّ لَوۡ اَنَّ بَیۡنَہَا وَ بَیۡنَہٗۤ اَمَدًۢا بَعِیۡدًا ؕ وَ یُحَذِّرُکُمُ اللّٰہُ نَفۡسَہٗ ؕ وَ اللّٰہُ رَءُوۡفٌۢ بِالۡعِبَادِ
On the Day when every person will be confronted with all the good he has done, and all the evil he has done, he will wish that there was a great distance between him and his evil. And Allah warns you against Himself and Allah is full of Kindness to His slaves.
[Aal-Imraan : 30]
"You have killed me, O Mansur," said Abdul-Malik. "O Mansur, what does, 'And Allah warns you against Himself' mean?"
"It means His Punishment," said Mansurرحمة لله علیھ.
"And what is the meaning of, 'every person will be confronted with all the good he has done,'?" asked Abdul-Malik?
"It means that every person will be confronted on the Day of Resurrection by all of his deeds, the largest of them and the tiniest of them. Allah Ta’ala will not leave out or forget any of it."
Abdul Malik then continued to cry until, being overcome with fear, he fainted.
