Full Sharh — Mishkat al-Masabih 1916
وَعَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صلى الله عَلَيْهِ وَسلم: «من ذرعه الْقَيْء وَهُوَ صَائِمٌ فَلَيْسَ عَلَيْهِ قَضَاءٌ وَمَنِ اسْتَقَاءَ عَمْدًا فَلْيَقْضِ» . رَوَاهُ التِّرْمِذِيُّ وَأَبُو دَاوُدَ وَابْنُ مَاجَهْ وَالدَّارِمِيُّ. وَقَالَ التِّرْمِذِيُّ: هَذَا حَدِيثٌ غَرِيبٌ لَا نَعْرِفُهُ إِلَّا مِنْ حَدِيثِ عِيسَى بْنِ يُونُس. وَقَالَ مُحَمَّد يَعْنِي البُخَارِيّ لَا أرَاهُ مَحْفُوظًا
English Translation
He reported God’s messenger as saying, "If one has a sudden attack of vomiting while he is fasting no atonement is required of him, but if he vomits intentionally he must make atonement." Tirmidhi, Abu Dawud, Ibn Majah and Darimi transmitted it. Tirmidhi said this is a gharib tradition which he knew only among the traditions of ‘Isa. b. Yunus, and that Muhammad, i.e. Bukhari, said he did not consider it one which was held in estimation.
