“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.’”
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 ﷺ لأُبْلِغَنَّ أَوْ لأُبْلِيَنَّ فِي أَبِي أُمَامَةَ عُذْرًا فَكَوَاهُ بِيَدِهِ فَمَاتَ فَقَالَ النَّبِيُّ ﷺ مِيتَةَ سُوءٍ لِلْيَهُودِ يَقُولُونَ أَفَلاَ دَفَعَ عَنْ صَاحِبِهِ وَمَا أَمْلِكُ لَهُ وَلاَ لِنَفْسِي شَيْئًا
