That he recited Umm-ul-Qur'an (Sura Fatiha), and he collected his spittle and he applied that and the person became all right.
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، وَأَبُو بَكْرِ بْنُ نَافِعٍ كِلاَهُمَا عَنْ غُنْدَرٍ، مُحَمَّدِ بْنِ جَعْفَرٍ عَنْ شُعْبَةَ، عَنْ أَبِي بِشْرٍ، بِهَذَا الإِسْنَادِ وَقَالَ فِي الْحَدِيثِ فَجَعَلَ يَقْرَأُ أُمَّ الْقُرْآنِ وَيَجْمَعُ بُزَاقَهُ وَيَتْفُلُ فَبَرَأَ الرَّجُلُ ‏.‏
