Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 2|Chapter 8
وَ رَوَى جَمِيلٌ عَنْ زُرَارَةَ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ قَالَ: قُلْتُ لَهُ اَلرَّجُلُ يَشْتَرِي مِنَ اَلرَّجُلِ اَلْمَتَاعَ ثُمَّ يَدَعُهُ عِنْدَهُ يَقُولُ حَتَّى آتِيَكَ بِثَمَنِهِ فَقَالَ "إِنْ جَاءَ فِيمَا بَيْنَهُ وَ بَيْنَ ثَلاَثَةِ أَيَّامٍ وَ إِلاَّ فَلاَ بَيْعَ لَهُ".
Jamil narrated from Zurarah, from Abu Ja'far Imam Muhammad ibn Ali Al-Baqir عليه السلام, who said: I asked him about a man who buys merchandise from another man and then leaves it with him, saying, "I will bring you its price." Imam عليه السلام said: "If he brings the payment within three days, then the sale is valid; otherwise, there is no sale for him."
