عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ رَضِيَ اللَّهُ عَنْهُمَا أَنَّهُمْ كَانُوا لَا يَضَعُونَ أَيْدِيَهُمْ فِي الطَّعَامِ حَتَّى يَكُونَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ هُوَ يَبْدَأُ
Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) narrates that the Companions would not begin eating until the Noble Prophet (peace and blessings be upon him) started eating.
