Compiled by Imam Abu Isa at-Tirmidhi
حَدَّثَنَا عَبْدُ بْنُ حُمَيْدٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، عَنْ مَعْمَرٍ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ، رضى الله عنه قَالَ أُنْزِلَتْ عَلَى النَّبِيِّ صلى الله عليه وسلمَ : (ليغْفِرَ لَكَ اللَّهُ مَا تَقَدَّمَ مِنْ ذَنْبِكَ وَمَا تَأَخَّرَ ) مَرْجِعَهُ مِنَ الْحُدَيْبِيَةِ فَقَالَ النَّبِيُّ صلى الله عليه وسلم " لَقَدْ أُنْزِلَتْ عَلَىَّ آيَةٌ أَحَبُّ إِلَىَّ مِمَّا عَلَى الأَرْضِ ثُمَّ قَرَأَهَا النَّبِيُّ صلى الله عليه وسلم عَلَيْهِمْ فَقَالُوا هَنِيئًا مَرِيئًا يَا نَبِيَّ اللَّهِ قَدْ بَيَّنَ اللَّهُ لَكَ مَاذَا يُفْعَلُ بِكَ فَمَاذَا يُفْعَلُ بِنَا فَنَزَلَتْ عَلَيْهِ : ( ليُدْخِلَ الْمُؤْمِنِينَ وَالْمُؤْمِنَاتِ جَنَّاتٍ تَجْرِي مِنْ تَحْتِهَا الأَنْهَارُ ) حَتَّى بَلَغَ : (فوزًا عَظِيمًا ) قَالَ هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ وَفِيهِ عَنْ مُجَمِّعِ بْنِ جَارِيَةَ .
"While the Messenger of Allah (ﷺ) was returning from Al-Hudaibiyyah it was revealed to him, 'That Allah may forgive you your sins of the past and the future (48:2).' So the Prophet (ﷺ) said: 'An Ayah has been revealed to me which is dearer to me than whatever is upon the earth.' Then the Prophet (ﷺ) recited it for them and they said: 'Congratulations O Messenger of Allah! Allah has explained what He will do with you, but what will He do with us?' So (the following) was revealed: 'That He may admit the believing men and the believing women into Gardens under which rivers flow' up to (His Saying) 'a supreme success (48:5).'"
