Muhammad bin ‘Abdur-Rahman bin Sa’d bin Zurarah Al-Ansari said:

“I heard my paternal uncle Yahya – and I have not seen a man among us like him – tell the people that Sa'd bin Zurarah, who was the grandfather of Muhammad through his mother, was suffering from pain in his throat, known as croup. The Prophet (ﷺ) said: ‘I shall do my best for Abu Umamah.’ Such that I will be excused (i.e., free of blame if he is not healed). And he cauterized him with his own hand, but he died. The Prophet (ﷺ) said: ‘May the Jews be doomed! They will say: “Why could he not avert death from his Companions?” But I have no power to do anything for him or for my own self.’”

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَمُحَمَّدُ بْنُ بَشَّارٍ، قَالاَ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، غُنْدَرٌ حَدَّثَنَا شُعْبَةُ، ح وَحَدَّثَنَا أَحْمَدُ بْنُ سَعِيدٍ الدَّارِمِيُّ، حَدَّثَنَا النَّضْرُ بْنُ شُمَيْلٍ، حَدَّثَنَا شُعْبَةُ، حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ الرَّحْمَنِ بْنِ سَعْدِ بْنِ زُرَارَةَ الأَنْصَارِيُّ، قَالَ سَمِعْتُ عَمِّي، يَحْيَى - وَمَا أَدْرَكْتُ رَجُلاً مِنَّا بِهِ شَبِيهًا يُحَدِّثُ النَّاسَ أَنَّ سَعْدَ بْنَ زُرَارَةَ - وَهُوَ جَدُّ مُحَمَّدٍ مِنْ قِبَلِ أُمِّهِ أَنَّهُ أَخَذَهُ وَجَعٌ فِي حَلْقِهِ يُقَالُ لَهُ الذُّبْحَةُ فَقَالَ النَّبِيُّ ـ صلى الله عليه وسلم ـ ‏"‏ لأُبْلِغَنَّ أَوْ لأُبْلِيَنَّ فِي أَبِي أُمَامَةَ عُذْرًا ‏"‏ ‏.‏ فَكَوَاهُ بِيَدِهِ فَمَاتَ فَقَالَ النَّبِيُّ ـ صلى الله عليه وسلم ـ ‏"‏ مِيتَةَ سُوءٍ لِلْيَهُودِ يَقُولُونَ أَفَلاَ دَفَعَ عَنْ صَاحِبِهِ ‏.‏ وَمَا أَمْلِكُ لَهُ وَلاَ لِنَفْسِي شَيْئًا ‏"‏ ‏.‏
