1- مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ مُوسَى بْنِ بَكْرٍ عَنِ الْفُضَيْلِ قَالَ قَالَ غُلامٌ لأبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) إِنِّي كُنْتُ قُلْتُ لِمَوْلايَ بِعْنِي بِسَبْعِمِائَةِ دِرْهَمٍ وَأَنَا أُعْطِيكَ ثَلاثَمِائَةِ دِرْهَمٍ فَقَالَ لَهُ أَبُو عَبْدِ اللهِ (عَلَيْهِ السَّلام) إِنْ كَانَ لَكَ يَوْمَ شَرَطْتَ أَنْ تُعْطِيَهُ شَيْءٌ فَعَلَيْكَ أَنْ تُعْطِيَهُ وَإِنْ لَمْ يَكُنْ لَكَ يَوْمَئِذٍ شَيْءٌ فَلَيْسَ عَلَيْكَ شَيْءٌ.
1. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from Musa ibn Bakr from al-Fudayl who has said the following: “Once, a slave said to abu ‘ Abd Allah (a.s.), ‘I had said to my master, “Sell me for seven hundred dirham, I pay you three hundred dirham.’” Abu ‘Abd Allah (a.s.), said, ‘If you owned something on the day you made the condition then you must pay, and if you did not have anything on that day, there is nothing on you.’”
