Sahih Muslim 214
حَدَّثَنِي أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا حَفْصُ بْنُ غِيَاثٍ، عَنْ دَاوُدَ، عَنِ الشَّعْبِيِّ، عَنْ مَسْرُوقٍ، عَنْ عَائِشَةَ، قَالَتْ قُلْتُ يَا رَسُولَ اللَّهِ ابْنُ جُدْعَانَ كَانَ فِي الْجَاهِلِيَّةِ يَصِلُ الرَّحِمَ وَيُطْعِمُ الْمِسْكِينَ فَهَلْ ذَاكَ نَافِعُهُ قَالَ " لاَ يَنْفَعُهُ إِنَّهُ لَمْ يَقُلْ يَوْمًا رَبِّ اغْفِرْ لِي خَطِيئَتِي يَوْمَ الدِّينِ " .
Abu Bakr ibn Abi Shayba narrated to me: Hafs ibn Ghiyath narrated to us, from Dawud, from al-Sha‘bi, from Masruq, from ‘A’isha, who said: I asked, ‘Messenger of Allah, Ibn Jud‘an used to maintain family ties and feed the poor in the pre-Islamic period. Will that benefit him?’ He said, ‘It will not benefit him, because he never said, “My Lord, forgive my sin on the Day of Judgment.”’
Translation notes
The source explicitly states that Ibn Jud‘an’s charitable deeds did not benefit him because he never made this supplication.
