مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ عَنْ مُحَمَّدِ بْنِ إِسْمَاعِيلَ عَنْ صَالِحِ بْنِ عُقْبَةَ عَنْ سُلَيْمَانَ بْنِ صَالِحٍ قَالَ قُلْتُ لِأَبِي عَبْدِ اللَّهِ ( عليه السلام ) مَا أَدْنَى مَا يَجِي‏ءُ مِنَ الْإِسْرَافِ قَالَ ابْتِذَالُكَ ثَوْبَ صَوْنِكَ وَ إِهْرَاقُكَ فَضْلَ إِنَائِكَ وَ أَكْلُكَ التَّمْرَ وَ رَمْيَكَ بِالنَّوَى هَاهُنَا وَ هَاهُنَا .
2. Muhammad ibn Yahya Muhammad ibn al-Husayn from Muhammad ibn ’Isma‘il from Salih ibn ‘Uqbah from Sulayman ibn Salih who has said the following: “I once asked abu ‘ Abd Allah , about the least degree of squandering. He (the Imam) said, ‘It is misuse of protective clothes, throwing away the remaining water in your bowl and when eating dates throwing the date-stone here and there.’”
