"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.
قَالَ رَسُولُ اللَّهِ ﷺ لَيْسَ مِنَ الْبِرِّ الصِّيَامُ فِي السَّفَرِ قَالَ أَبُو عَبْدِ الرَّحْمَنِ هَذَا خَطَأٌ وَالصَّوَابُ الَّذِي قَبْلَهُ لاَ نَعْلَمُ أَحَدًا تَابَعَ ابْنَ كَثِيرٍ عَلَيْهِ
