مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنْ إِبْرَاهِيمَ بْنِ أَبِي مَحْمُودٍ قَالَ قَالَ لَنَا الرِّضَا ( عليه السلام ) أَيُّ الْإِدَامِ أَحْرَى فَقَالَ بَعْضُنَا اللَّحْمُ وَ قَالَ بَعْضُنَا الزَّيْتُ وَ قَالَ بَعْضُنَا اللَّبَنُ فَقَالَ هُوَ ( عليه السلام ) لَا بَلِ الْمِلْحُ وَ لَقَدْ خَرَجْنَا إِلَى نُزْهَةٍ لَنَا وَ نَسِيَ بَعْضُ الْغِلْمَانِ الْمِلْحَ فَذَبَحُوا لَنَا شَاةً مِنْ أَسْمَنِ مَا يَكُونُ فَمَا انْتَفَعْنَا بِشَيْ‏ءٍ حَتَّى انْصَرَفْنَا .
7. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from Ibrahim ibn abu Mahmud who has said the following: “Al-Rida’ , once asked us, ‘Which food is of greater preference?’ Certain ones among us said that it is meat, others said that it is oil, yet others said it is milk. He (the Imam) said, ‘No, it is salt.’ We then went outside for freshness and a certain one of servants forgot salt. They slaughtered a sheep for us which was the most fat one and we could not benefit thereof anything until we returned back.’”
