“If a servant performs

Abu Musa reported: I heard the Prophet, peace be upon him, say on more than two occasions, “If a servant performs a good deed, but then is occupied by sickness or travel, it will be written for him as a good deed like he used to do when he was healthy and settled.”
[Sunan Abu Dawud, Book 20, Number 3091, Sahih]

عَنْ أَبِي مُوسَى قَالَ  سَمِعْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ غَيْرَ مَرَّةٍ وَلَا مَرَّتَيْنِ يَقُولُ إِذَا كَانَ الْعَبْدُ يَعْمَلُ عَمَلًا صَالِحًا فَشَغَلَهُ عَنْهُ مَرَضٌ أَوْ سَفَرٌ كُتِبَ لَهُ كَصَالِحِ مَا كَانَ يَعْمَلُ وَهُوَ صَحِيحٌ مُقِيمٌ

Once I passed the night in the house of my aunt Maimuna. The Prophet
