from Samurah bin Jundab that he said: "We were with the Prophet ﷺ and we would take turns (eating) from a bowl from the morning till the evening. Ten would stand and ten would sit." We said: "So what was filling it up?' He said: "What are you amazed at? It wasn't filled up from anywhere but here, and he pointed with his hand towards the sky." (Using translation from Tirmidhī 3625)  

كُنَّا مَعَ النَّبِيِّ ﷺ نَتَدَاوَلُ صَحْفَةَ مِنْ غُدْوَةٍ حَتَّى اللَّيْلِ يَقُومُ عَشَرَةٌ وَيَقْعُدُ عَشَرَةٌ قُلْنَا فَمَا كَانَتْ تُمَدُّ؟ قَالَ «مِنْ أَيِّ شَيْءٍ تَعْجَبُ مَا كَانَتْ تُمَدُّ إِلَّا مِنْ هَاهُنَا وَأَشَارَ بِيَدِهِ إِلَى السَّمَاءِ»
