Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 2|Chapter 38
وَ رُوِيَ عَنْ سَعْدِ بْنِ اَلْحَسَنِ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ: أَنَّهُ سُئِلَ عَنِ اَلرَّجُلِ يَحْلِفُ أَنْ لاَ يَبِيعَ سِلْعَتَهُ بِكَذَا وَ كَذَا ثُمَّ يَبْدُو لَهُ قَالَ "يَبِيعُ وَ لاَ يُكَفِّرُ".
It is narrated from Sa'd ibn al-Hasan, from Abu Abdillah عليه السلام, that Imam عليه السلام was asked about a man who swears that he will not sell his merchandise for a certain price, but then later changes his mind. Imam عليه السلام said: "He may sell it, and no expiation is required."
