Imam al-Sadiq (AS) said regarding a man who has a commodity and marks it for sale at a certain price; he would sell it to any silent buyer for the marked price, but he would make a better offer for the bargainer: ‘If he were to make a better offer for two or three men, it would not be a problem; but if he does that for everyone who bargains with him and not for non-bargainers, his deed would not appeal to me. He must be singular in his sale.
الإمامُ الصّادقُ (عَلَيهِ الّسَلامُ) ـ في رجُلٍ عِندَهُ بَيْعٌ، فَسَعّرَهُ سِعْراً مَعلوماً، فمَنْ سَكَتَ عنهُ مِمّنْ يَشْتري مِنهُ باعَهُ بذلكَ السِّعْرِ، ومَن ماكَسَهُ وأبى أنْ يَبْتاعَ مِنهُ زادَهُ ـ: لو كانَ يَزيدُ الرَّجُلَينِ والثَّلاثةَ لم يَكُنْ بذلكَ بَأسٌ، فأمَّا أنْ يَفعَلَهُ بمَن أبى علَيهِ وكايَسَهُ ويَمْنَعَهُ مِمَّن لَم يَفْعَلْ ذلك فلا يُعْجِبُني إلّا أنْ يَبيعَهُ بَيْعاً واحِداً.
