(1) Plural of basur (hemorrhoid). The word is transmitted with either the letter ba or with nun. With ba it denotes a swelling inside the rectum; with nun it refers to a malignant ulcer that will not heal so long as the corruption remains (Fath). (2) Reported by al-Bukhari 2/469; Abu Dawud 1/150; al-Tirmidhi 2/208; Ibn Majah 1/369; al-Tahawi, al-Mushkil 2/281-82; al-Daraqutni no. 146; al-Hakim 1/315; al-Bayhaqi 2/304; and Ahmad 2/426, through Ibrahim ibn Tahman → Husayn al-Muallim → Abd Allah ibn Buraydah → the Prophet. Al-Hakim judged it “sound according to the criteria of the two shaykhs, though they did not record it in this wording,” but he was mistaken in claiming that al-Bukhari omitted it. Al-Zaylaʿi 2/175 and Ibn Hajar, al-Talkhis 3/285, ascribe it to al-Nasaʾi, adding: “If you are unable, then lie on your back—‘Allah does not burden a soul beyond its capacity.’” I did not find it in al-Sunan al-Sughra; it is probably in his al-Kubra. Ibn Hajar 2/470 comments: “This hadith is used by those who say that a sick person should not move from standing to sitting until he is completely unable to stand.” Qadi Iyad transmits this view from al-Shafiʿi, and from Malik and Ahmad. Ahmad’s son Abd Allah reports that his father was asked about it… (The words inside square brackets were omitted in the author’s draft.)
