عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُ عَنْ سَعْدِ بْنِ عُبَادَةَ رَضِيَ اللَّهُ عَنْهُ أَنَّهُ أَتَى النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَقَالَ: إِنَّ أُمِّي مَاتَتْ وَعَلَيْهَا نَذْرٌ، أَفَيُجْزِي عَنْهَا أَنْ أُعْتِقَ عَنْهَا؟ قَالَ: ((أَعْتِقْ عَنْ أُمِّكَ))
It is narrated from Sayyiduna Sa’d bin ‘Ubadah (may Allah be pleased with him) that he came to the Noble Prophet (peace and blessings be upon him) and said: My mother has passed away, and she had a vow upon her. If I free a slave on her behalf, will it suffice for her? The Prophet (peace and blessings be upon him) said: Free (a slave) on behalf of your mother.
