]وَعَنْ عِمْرَانَ بْنِ حُصَيْنٍ ‏-رَضِيَ اَللَّهُ عَنْهُمَا‏- قَالَ : { قَالَ لِيَ اَلنَّبِيُّ ‏- صلى الله عليه وسلم ‏-" صَلِّ قَائِمًا , فَإِنْ لَمْ تَسْتَطِعْ فَقَاعِدًا , فَإِنْ لَمْ تَسْتَطِعْ فَعَلَى جَنْبٍ } رَوَاهُ اَلْبُخَارِيُّ .‏ 1‏
'Imran bin Husain (RA):

Allah's Messenger (ﷺ) said: "Pray standing and if you are unable, pray sitting and if you cannot, pray lying on your side, [otherwise pray by signs]." [Reported by al-Bukhari, (without the final words)].
