4022 - وَ رَوَى مُحَمَّدُ بْنُ قَيْسٍ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ قَالَ قَالَ أَمِيرُ اَلْمُؤْمِنِينَ عَلَيْهِ اَلسَّلاَمُ : "مَنْ بَاعَ سِلْعَةً فَقَالَ إِنَّ ثَمَنَهَا كَذَا وَ كَذَا يَداً بِيَدٍ وَ ثَمَنُهَا كَذَا وَ كَذَا نَظِرَةً فَخُذْهَا بِأَيِّ ثَمَنٍ شِئْتَ وَ اِجْعَلْ صَفْقَتَهَا وَاحِدَةً " فَقَالَ "لَيْسَ لَهُ إِلاَّ أَقَلُّهُمَا وَ إِنْ كَانَتْ نَظِرَةً ".
Hadith.4022 - Muhammad ibn Qays narrated from Abu Ja'far Imam Muhammad ibn Ali Al-Baqir (as) that Commander of the Faithful (as) said: "Whoever sells a commodity and says, 'Its price is such and such if paid immediately, and its price is such and such if paid later,' then take it at whichever price you wish and make it a single transaction." Then Imam (as) said: "He is only entitled to the lower price, even if it is on credit."
