[Machine] A man came to the Messenger of Allah ﷺ and said, "I can provide you with food." So the Messenger of Allah ﷺ fed him and gave him barley to drink. The man and his wife and their companion kept eating from it until they were filled. The Messenger of Allah ﷺ said, "If you had not been satisfied, I would have eaten from it and it would have sufficed for you."  

جَاءَ رَجُلٌ إِلَى رَسُولِ اللهِ ﷺ يَسْتَطْعِمُهُ فَأَطْعَمَهُ رَسُولُ اللهِ ﷺ وَسْقَ شَعِيرٍ فَمَا زَالَ الرَّجُلُ يَأْكُلُ مِنْهُ هُوَ وَامْرَأَتُهُ وَوَصِيفٌ لَهُمْ حَتَّى كَالُوهُ فَقَالَ رَسُولُ اللهِ ﷺ لَوْ لَمْ تَكِيلُوهُ لَأَكَلْتُمْ مِنْهُ وَلَقَامَ لَكُمْ  

Had you not weighed it, you would be eating out of it and it would have remained intact for you. (Using translation from Muslim 2281)   

عَنِ النَّبِيِّ ﷺ أَنَّهُ أَتَاهُ رَجُلٌ يَسْتَطْعِمُهُ فَأَطْعَمَهُ شَطْرَ وَسْقِ شَعِيرٍ فَمَا زَالَ الرَّجُلُ يَأْكُلُ مِنْهُ هُوَ وَامْرَأَتُهُ وَوَصِيفٌ لَهُمْ حَتَّى كَالُوهُ فَقَالَ النَّبِيُّ ﷺ لَوْ لَمْ تَكِيلُوهُ لَأَكَلْتُمْ مِنْهُ وَلَقَامَ لَكُمْ
