FORGIVENESS OF CONCEALED SINS H 434 "On the Day of Judgement, a believer will approach his Lord and He will encompass him in His Mercy. He will question him about his sins saying: 'Do you recognize this sin and this sin?' He will answer: 'Lord, I recognize them.' Then He will say: 'I concealed them for you in the world, and I forgive you today.' Thereafter the record of his good works will be handed to him." R 434 Bukhari and Muslim with a chain up to ibn Omar who related that he heard the Prophet, praise and peace be upon him, say this hadith
433- وعن ابن عمر رضي الله عنهما ، قَالَ : سَمِعْتُ رسولَ الله صلى الله عليه وآله وسلم ، يقول : "يُدْنَى المُؤْمِنُ يَوْمَ القِيَامَة مِنْ رَبِّهِ حَتَّى يَضَعَ كَنَفَهُ عَلَيهِ ، فَيُقَرِّرُهُ بذُنُوبِهِ ، فيقولُ : أتعرِفُ ذَنْبَ كَذَا ؟ أتَعرفُ ذَنْبَ كَذَا ؟ فيقول : رَبِّ أعْرِفُ ، قَالَ : فَإنِّي قَدْ سَتَرْتُهَا عَلَيْكَ في الدُّنْيا ، وَأنَا أغْفِرُهَا لَكَ اليَومَ ، فَيُعْطَى صَحيفَةَ حَسَنَاتِهِ" مُتَّفَقٌ عَلَيهِ . " كَنَفَهُ" : سَتْرُهُ وَرَحْمَتُهُ .
