Arabic (Original)
حَدَّثَنَا سُفْيَانُ عَنْ عَبْدِ الْكَرِيمِ قَالَ أَخْبَرَنِي زِيَادُ بْنُ أَبِي مَرْيَمَ عَنْ عَبْدِ اللَّهِ بْنِ مَعْقِلِ بْنِ مُقَرِّنٍ قَالَ دَخَلْتُ مَعَ أَبِي عَلَى عَبْدِ اللَّهِ بْنِ مَسْعُودٍ فَقَالَ أَنْتَ سَمِعْتَ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ النَّدَمُ تَوْبَةٌ قَالَ نَعَمْ وَقَالَ مَرَّةً سَمِعْتُهُ يَقُولُ النَّدَمُ تَوْبَةٌ.
English Translation
Sufyan told us, from Abd al-Karim, who said: Ziyad ibn Abi Maryam informed me, from Abdullah ibn Ma'qil ibn Muqarrin, who said: "I entered with my father upon Abdullah ibn Mas'ud, and he said: 'Did you hear the Prophet, peace and blessings be upon him, say: "Remorse is repentance"?' He said: 'Yes.'" And he said another time: "I heard him say: 'Remorse is repentance.'"
