6- مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ مَحْبُوبٍ عَنْ جَمِيلٍ عَنْ فُضَيْلٍ عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) قَالَ
قُلْتُ لَهُ مَا الشَّرْطُ فِي الْحَيَوَانِ فَقَالَ إِلَى ثَلاثَةِ أَيَّامٍ لِلْمُشْتَرِي قُلْتُ فَمَا الشَّرْطُ فِي غَيْرِ الْحَيَوَانِ قَالَ الْبَيِّعَانِ بِالْخِيَارِ مَا لَمْ يَفْتَرِقَا فَإِذَا افْتَرَقَا فَلا خِيَارَ بَعْدَ الرِّضَا مِنْهُمَا.
6. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn Mahbub from Jamil from Fudayl who has said the following:
“This is concerning my question before abu ‘Abd Allah 
, ‘What is a stipulation in a deal for animals ? 5 He (the Imam) replied, ‘It is valid for three days in favor of a buyer . 5 I then asked, ‘What is it in a deal for non-animal ? 5 He (the Imam) replied, ‘A buyer and a seller have the choice to dismiss a deal until they depart each other. After their departing each other there is no choice after their agreement.’”
