When they finished (food), the said: If some people enter the house of a man, his food is eaten and his drink is drunk, and they supplicate (to Allah) for him, this is his reward.  

أبو داود:٣٨٥٣حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ حَدَّثَنَا أَبُو أَحْمَدَ حَدَّثَنَا سُفْيَانُ عَنْ يَزِيدَ أَبِي خَالِدٍ الدَّالاَنِيِّ عَنْ رَجُلٍ عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ قَالَ

صَنَعَ أَبُو الْهَيْثَمِ بْنُ التَّيْهَانِ لِلنَّبِيِّ ﷺ طَعَامًا فَدَعَا النَّبِيَّ ﷺ وَأَصْحَابَهُ فَلَمَّا فَرَغُوا قَالَ أَثِيبُوا أَخَاكُمْ قَالُوا يَا رَسُولَ اللَّهِ وَمَا إِثَابَتُهُ قَالَ إِنَّ الرَّجُلَ إِذَا دُخِلَ بَيْتُهُ فَأُكِلَ طَعَامُهُ وَشُرِبَ شَرَابُهُ فَدَعَوْا لَهُ فَذَلِكَ إِثَابَتُهُ
