1162. hadíth
وَ كَانَ عَلِيُّ بْنُ اَلْحُسَيْنِ زَيْنُ اَلْعَابِدِينَ عَلَيْهِ اَلسَّلاَمُ يَقُولُ لِقَهْرَمَانِهِ إِذَا أَرَدْتَ أَنْ تَشْتَرِيَ لِي مِنْ حَوَائِجِ اَلْحَجِّ شَيْئاً فَاشْتَرِ وَ لاَ تُمَاكِسْ
Imam Ali ibn Al-Hussain Zayn Al-Abidin (a.s) used to say to his steward: "If you intend to buy something for me from the needs of Hajj, then buy it and do not bargain."
