[Machine] The Messenger of Allah ﷺ said: The food of the first day is a duty, and the food of the second day is the same. And in the narration of As-Sulami, the food of one day is a duty, the food of two days is a recommended act, and the food of the third day is a virtue and a reward. And whoever feeds others will be fed by Allah and the Sulami did not mention his saying of "reward".
قَالَ رَسُولُ اللهِ ﷺ طَعَامُ أَوَّلَ يَوْمٍ حَقٌّ وَالثَّانِيَ مِثْلَهُ وَفِي رِوَايَةِ السُّلَمِيِّ طَعَامُ يَوْمٍ حَقٌّ وَطَعَامُ يَوْمَيْنِ سُنَّةٌ وَطَعَامُ الْيَوْمِ الثَّالِثِ سُمْعَةٌ وَرِئَاءٌ وَمَنْ يُسَمِّعْ يُسَمِّعِ اللهُ بِهِ وَلَمْ يَذْكُرِ السُّلَمِيُّ قَوْلَهُ رِئَاءٌ
