Wahshi b. Harb, on his father’s authority, said his grandfather told of God's messenger's Companions saying, "Messenger of God, we eat but are not satisfied." He suggested that they ate separately, and when they replied that that was so he said, "If you gather together at your food and mention God’s name you will be blessed in it." Abu Dawud transmitted it.

وَعَنْ وَحْشِيِّ بْنِ حَرْبٍ عَنْ أَبِيهِ عَنْ جَدِّهِ: إِنَّ أَصْحَابَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالُوا: يَا رَسُولَ اللَّهِ إِنَّا نَأْكُلُ وَلَا نَشْبَعُ قَالَ: «فَلَعَلَّكُمْ تَفْتَرِقُونَ؟» قَالُوا: نَعَمْ قَالَ: «فَاجْتَمِعُوا عَلَى طَعَامِكُمْ وَاذْكُرُوا اسْمَ اللَّهِ يُباركْ لكم فِيهِ» . رَوَاهُ التِّرْمِذِيّ
