I said, "O Messenger of Allah ﷺ! We have slaughtered a young sheep of ours and have ground one Sa of barley. So, I invite you along with some persons." So, the Prophet ﷺ said in a loud voice, "O the people of the Trench! Jabir had prepared "Sur" so come along."
قُلْتُ يَا رَسُولَ اللَّهِ ذَبَحْنَا بُهَيْمَةً لَنَا وَطَحَنْتُ صَاعًا مِنْ شَعِيرٍ فَتَعَالَ أَنْتَ وَنَفَرٌ فَصَاحَ النَّبِيُّ ﷺ فَقَالَ يَا أَهْلَ الْخَنْدَقِ إِنَّ جَابِرًا قَدْ صَنَعَ سُؤْرًا فَحَىَّ هَلاً بِكُمْ
