Narrated 'Amr b. Suh'aib:

On his father's authority, said that his grandfather told that Al-'As ibn Wa'il left his will that a hundred slaves should be emancipated on his behalf. His son Hisham emancipated fifty slaves and his son Amr intended to emancipate the remaining fifty on his behalf, but he said: I should ask first the Messenger of Allah ﷺ. He, therefore, came to the Prophet ﷺ and said: Messenger of Allah, my father left in his will that a hundred slaves should be emancipated on his behalf and Hisham has emancipated fifty on his behalf and fifty remain. Shall I emancipate them on his behalf? The Messenger of Allah ﷺ said: Had he been a Muslim and you had emancipated slaves on his behalf, or given sadaqah on his behalf, or performed the pilgrimage, that would have reached him.

حَدَّثَنَا الْعَبَّاسُ بْنُ الْوَلِيدِ بْنِ مَزْيَدٍ، أَخْبَرَنِي أَبِي، حَدَّثَنَا الأَوْزَاعِيُّ، حَدَّثَنِي حَسَّانُ بْنُ عَطِيَّةَ، عَنْ عَمْرِو بْنِ شُعَيْبٍ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، أَنَّ الْعَاصَ بْنَ وَائِلٍ، أَوْصَى أَنْ يُعْتَقَ، عَنْهُ مِائَةُ رَقَبَةٍ فَأَعْتَقَ ابْنُهُ هِشَامٌ خَمْسِينَ رَقَبَةً فَأَرَادَ ابْنُهُ عَمْرٌو أَنْ يَعْتِقَ عَنْهُ الْخَمْسِينَ الْبَاقِيَةَ فَقَالَ حَتَّى أَسْأَلَ رَسُولَ اللَّهِ ﷺ فَأَتَى النَّبِيَّ ﷺ فَقَالَ يَا رَسُولَ اللَّهِ إِنَّ أَبِي أَوْصَى بِعِتْقِ مِائَةِ رَقَبَةٍ وَإِنَّ هِشَامًا أَعْتَقَ عَنْهُ خَمْسِينَ وَبَقِيَتْ عَلَيْهِ خَمْسُونَ رَقَبَةً أَفَأُعْتِقُ عَنْهُ فَقَالَ رَسُولُ اللَّهِ ﷺ " إِنَّهُ لَوْ كَانَ مُسْلِمًا فَأَعْتَقْتُمْ عَنْهُ أَوْ تَصَدَّقْتُمْ عَنْهُ أَوْ حَجَجْتُمْ عَنْهُ بَلَغَهُ ذَلِكَ " .
