"From Imran bin Husain who said: 'I asked Messenger of Allah (S) about Salat for a sick person. He said: "He performs Salat standing, if he is not able then sitting, if he is not able then on his side."
سَأَلْتُ رَسُولَ اللَّهِ ﷺ عَنْ صَلاَةِ الْمَرِيضِ فَقَالَ صَلِّ قَائِمًا فَإِنْ لَمْ تَسْتَطِعْ فَقَاعِدًا فَإِنْ لَمْ تَسْتَطِعْ فَعَلَى جَنْبٍ حَدَّثَنَا بِذَلِكَ هَنَّادٌ حَدَّثَنَا وَكِيعٌ عَنْ إِبْرَاهِيمَ بْنِ طَهْمَانَ عَنْ حُسَيْنٍ الْمُعَلِّمِ بِهَذَا الْحَدِيثِ
had piles, so I asked the Prophet ﷺ about the prayer. He said, "Pray while standing and if you can't, pray while sitting and if you cannot do even that, then pray Lying on your side."
كَانَتْ بِي بَوَاسِيرُ فَسَأَلْتُ النَّبِيَّ ﷺ عَنِ الصَّلاَةِ فَقَالَ صَلِّ قَائِمًا فَإِنْ لَمْ تَسْتَطِعْ فَقَاعِدًا فَإِنْ لَمْ تَسْتَطِعْ فَعَلَى جَنْبٍ
I had a fistula; so I asked the prophet ﷺ. He said: offer prayer in standing condition; if you are unable to do so, then in sitting condition: if you are then at your side(i.e, in lying condition).
كَانَ بِيَ النَّاصُورُ فَسَأَلْتُ النَّبِيَّ ﷺ فَقَالَ صَلِّ قَائِمًا فَإِنْ لَمْ تَسْتَطِعْ فَقَاعِدًا فَإِنْ لَمْ تَسْتَطِعْ فَعَلَى جَنْبٍ
“I suffered from Nasur* and I asked the Prophet ﷺ about prayer. He said: ‘Perform prayer standing; if you cannot, then sitting; and if you cannot then while lying on your side.’”
كَانَ بِي النَّاصُورُ فَسَأَلْتُ النَّبِيَّ ﷺ عَنِ الصَّلاَةِ فَقَالَ صَلِّ قَائِمًا فَإِنْ لَمْ تَسْتَطِعْ فَقَاعِدًا فَإِنْ لَمْ تَسْتَطِعْ فَعَلَى جَنْبٍ
I had a fistula; so I asked the prophet ﷺ. He said: offer prayer in standing condition; if you are unable to do so, then in sitting condition: if you are then at your side(i.e, in lying condition). (Using translation from Abū Dāʾūd 952)
كَانَ بِي النَّاصُورُ فَسَأَلْتُ النَّبِيَّ ﷺ عَنِ الصَّلَاةِ؟ فَقَالَ صَلِّ قَائِمًا فَإِنْ لَمْ تَسْتَطِعْ فَقَاعِدًا فَإِنْ لَمْ تَسْتَطِعْ فَعَلَى جَنْبٍ
