That the Messenger of Allah ﷺ passed by a pile of food. He put his fingers in it and felt wetness. He said: 'O owner of the food! What is this ?' He replied: 'It was rained upon O Messenger of Allah.' He said: 'Why not put it on top of the food so the people can see it?' Then he said: 'Whoever cheats, he is not one of us.'" He said: There are narrations on this topic from Ibn 'Umar, Abu Al-Hamra', Ibn 'Abbas, Buraidah, Abu Burdah bin Niyar, and Hudhaifah bin Al-Yaman.
أَنَّ رَسُولَ اللَّهِ ﷺ مَرَّ عَلَى صُبْرَةٍ مِنْ طَعَامٍ فَأَدْخَلَ يَدَهُ فِيهَا فَنَالَتْ أَصَابِعُهُ بَلَلاً فَقَالَ يَا صَاحِبَ الطَّعَامِ مَا هَذَا قَالَ أَصَابَتْهُ السَّمَاءُ يَا رَسُولَ اللَّهِ قَالَ أَفَلاَ جَعَلْتَهُ فَوْقَ الطَّعَامِ حَتَّى يَرَاهُ النَّاسُ ثُمَّ قَالَ مَنْ غَشَّ فَلَيْسَ مِنَّا قَالَ وَفِي الْبَابِ عَنِ ابْنِ عُمَرَ وَأَبِي الْحَمْرَاءِ وَابْنِ عَبَّاسٍ وَبُرَيْدَةَ وَأَبِي بُرْدَةَ بْنِ نِيَارٍ وَحُذَيْفَةَ بْنِ الْيَمَانِ
