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

[AI] From the Messenger of Allah ﷺ, it is narrated that he entered upon him and said, "Remove the pain, O Lord of the people, from Thabit ibn Qais ibn Shammas." Then, he took some soil from Buthan and placed it in a container that had water in it, and poured it onto him.

عَنْ رَسُولِ اللَّهِ ﷺ أَنَّهُ دَخَلَ عَلَيْهِ فَقَالَ «اكْشِفِ الْبَأْسَ رَبَّ النَّاسِ عَنْ ثَابِتِ بْنِ قَيْسِ بْنِ الشَّمَّاسِ» ثُمَّ أَخَذَ تُرَابًا مِنْ بُطْحَانَ فَجَعَلَهُ فِي قَدَحٍ فِيهِ مَاءٌ فَصَبَّهُ عَلَيْهِ

[AI] Narrated by the Prophet ﷺ , he entered upon him and said, "Remove the hardship, O Lord of the people, from Thabit ibn Qays ibn Shammas." Then he took some soil from a plate containing water and poured it on him.

عَنِ النَّبِيِّ ﷺ أَنَّهُ دَخَلَ عَلَيْهِ فَقَالَ «اكْشِفِ الْبَأْسَ رَبَّ النَّاسِ عَنْ ثَابِتِ بْنِ قَيْسِ بْنِ شَمَّاسٍ ثُمَّ أَخَذَ تُرَابًا مِنْ بَطْحَاءَ فِي قَدَحٍ فِيهِ مَاءٌ فَصَبَّهُ عَلَيْهِ»
