Hadith 2:353
Narrated 'Imran bin Husain (RA):
I suffered from piles. So I asked the Prophet (ﷺ) about the prayers. He said: "Pray standing; and if you are unable, (pray) sitting; and if you are unable, (pray) lying on your side." [Reported by al-Bukhari].
وَعَنْ عِمْرَانَ بْنِ حُصَيْنٍ رَضِيَ اَللَّهُ عَنْهُمَا قَالَ: { كَانَتْ بِي بَوَاسِيرُ, فَسَأَلْتُ اَلنَّبِيَّ - صلى الله عليه وسلم -عَنْ اَلصَّلَاةِ؟ فَقَالَ: "صَلِّ قَائِمًا, فَإِنْ لَمْ تَسْتَطِعْ فَقَاعِدًا, فَإِنْ لَمْ تَسْتَطِعْ فَعَلَى جَنْبٍ" } رَوَاهُ اَلْبُخَارِيُّ
