إِنَّ يَعْقُوبَ ع كَانَ لَهُ مُنَادٍ يُنَادِي كُلَّ غَدَاةٍ مِنْ مَنْزِلِهِ عَلَى فَرْسَخٍ أَلَا مَنْ أَرَادَ الْغَدَاءَ فَلْيَأْتِ إِلَى مَنْزِلِ يَعْقُوبَ وَ إِذَا أَمْسَى يُنَادِي أَلَا مَنْ أَرَادَ الْعَشَاءَ فَلْيَأْتِ إِلَى مَنْزِلِ يَعْقُوبَ.
“Abu ‘Abd Allah (a.s.), has said Ya’qub (a.s.), had an announcer who every morning announced from his house to three miles, ‘Those who want lunch can come to the house of Ya’qub.’ In the evening the announcement said, ’Those who want dinner can come to the house of Ya’qub.’”
