عَنْ زَيْدِ بْنِ أَرْقَمَ رَضِيَ اللَّهُ عَنْهُ قَالَ سَحَرَ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ رَجُلٌ مِنَ الْيَهُودِ قَالَ فَاشْتَكَى لِذَلِكَ أَيَّامًا قَالَ فَجَاءَ جِبْرِيلُ فَقَالَ إِنَّ رَجُلًا مِنَ الْيَهُودِ سَحَرَكَ عَقَدَ لَكَ عُقَدًا فِي بِئْرٍ كَذَا وَكَذَا فَأَرْسِلْ إِلَيْهَا مَنْ يَجِيءُ بِهَا فَبَعَثَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ عَلِيًّا رَضِيَ اللَّهُ عَنْهُ فَاسْتَخْرَجَهَا فَجَاءَ بِهَا فَحَلَّهَا قَالَ فَقَامَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ كَأَنَّمَا نُشِطَ مِنْ عِقَالٍ فَمَا ذَكَرَ لِذَلِكَ الْيَهُودِيِّ وَلَا رَآهُ فِي وَجْهِهِ قَطُّ حَتَّى مَاتَ
It is narrated from Sayyiduna Zaid bin Arqam (may Allah be pleased with him) that a man from among the Jews cast magic upon the Noble Prophet (peace and blessings be upon him), due to which he (peace and blessings be upon him) remained ill for several days. Eventually, Jibreel (peace be upon him) came and said: "A man from among the Jews has cast magic upon you and for this purpose, he has tied magical knots. This act of magic is placed in such-and-such well. Send someone to bring out this act." So the Messenger of Allah (peace and blessings be upon him) sent Sayyiduna Ali (may Allah be pleased with him), who brought it out and untied those knots. It was as if the Prophet (peace and blessings be upon him) had been released from a rope. The Prophet (peace and blessings be upon him) neither mentioned this matter to that Jew nor looked towards his face, until he died.
