The Messenger of Allah ﷺ entered upon Thabit ibn Qays. The version of Ahmad (ibn Salih) has: When he was ill He (the Prophet) said: Remove the harm, O Lord of men, from Thabit ibn Qays ibn Shammas. He then took some dust of Bathan, and put it in a bowel, and then mixed it with water and blew in it, and poured it on him. Abu Dawud said: Ibn al-Sarh said: Yusuf bin Muhammad is correct (and not Muhammad bin Yusuf)
عَنْ رَسُولِ اللَّهِ ﷺ أَنَّهُ دَخَلَ عَلَى ثَابِتِ بْنِ قَيْسٍ قَالَ أَحْمَدُ وَهُوَ مَرِيضٌ فَقَالَ اكْشِفِ الْبَاسَ رَبَّ النَّاسِ عَنْ ثَابِتِ بْنِ قَيْسٍ ثُمَّ أَخَذَ تُرَابًا مِنْ بَطْحَانَ فَجَعَلَهُ فِي قَدَحٍ ثُمَّ نَفَثَ عَلَيْهِ بِمَاءٍ وَصَبَّهُ عَلَيْهِ
