مَنِ اسْمُهُ يَحْيَى يَحْيَى بْنُ أَزْهَرَ أَسْعَدُ بْنُ زُرَارَةَ الْأَنْصَارِيُّ، عَنْهُ
[Machine] "That As'ad ibn Zurara, the grandfather of Muhammad, had a soreness in his throat called 'ad-Dhubhah.' The Messenger of Allah ﷺ said, "I will either give him an excuse or I will publicly expose him in the case of Abu Umamah." So he cured him with his hand, but then he died. The Messenger of Allah ﷺ said, "What a bad person he is to the Jews. They say, 'Shouldn't he have paid for his friend and whatever I possess for him and for myself from Allah?'"
أَنَّ أَسْعَدَ بْنَ زُرَارَةَ وَهُوَ جَدُّ مُحَمَّدٍ أَخَذَهُ وَجَعٌ فِي حَلْقِهِ يُقَالُ لَهُ الذُّبْحَةُ فَقَالَ رَسُولُ اللهِ ﷺ لَأُبْلِغَنَّ أَوْ لَأُبْلِيَنَّ فِي أَبِي أُمَامَةَ عُذْرًا فَكَوَاهُ بِيَدِهِ فَمَاتَ فَقَالَ رَسُولُ اللهِ ﷺ بِئْسَ الْمَيِّتُ لِلْيَهُودِ يَقُولُونَ أَفَلَا دَفَعَ عَنْ صَاحِبِهِ وَمَا أَمْلِكُ لَهُ وَلَا لِنَفْسِي مِنَ اللهِ شَيْئًا
