"The Messenger of Allah said: 'It is not righteousness to fast when traveling."' (Sahih) Abu 'Abdur-Rahman (An-Nasai) said: This is a mistake, and what is correct is the one that is before it. We do not know of anyone who followed up Ibn Kathir. (Using translation from Nasāʾī 2256)
قَالَ رَسُولُ اللهِ ﷺ «لَيْسَ مِنَ الْبِرِّ الصِّيَامُ فِي السَّفَرِ» قَالَ أَبُو عَبْدِ الرَّحْمَنِ هَذَا الْحَدِيثُ خَطَأٌ وَلَا نَعْلَمُ أَحَدًا تَابَعَ مُحَمَّدَ بْنَ كَثِيرٍ عَلَى هَذَا الْإِسْنَادِ وَاللهُ أَعْلَمُ وَالصَّوَابُ الَّذِي قَبْلَهُ
