وَعَنْ أَبِي مُوسَى
قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِذَا مَرِضَ الْعَبْدُ أَوْ سَافَرَ كُتِبَ لَهُ بِمِثْلِ مَا كَانَ يعْمل مُقيما صَحِيحا»
Abu Musa reported God’s messenger as saying, “When a man is ill or on a journey, what he was accustomed to do when staying at home and well will be recorded for him.”(This refers to his observance of salat, etc., cf. the traditions of Abdallah ibn Amr and Anas on p. 326.)
