Hadith #3

3- مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ حَدِيدٍ عَنْ جَمِيلِ بْنِ دَرَّاجٍ عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) فِي الرَّجُلِ يَشْتَرِي الطَّعَامَ ثُمَّ يَبِيعُهُ قَبْلَ أَنْ يَقْبِضَهُ قَالَ لا بَأْسَ وَيُوَكِّلُ الرَّجُلُ الْمُشْتَرِيَ مِنْهُ بِقَبْضِهِ وَكَيْلِهِ قَالَ لا بَأْسَ [بِذَلِكَ].

3. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn Hadid from Jamil ibn Darraj who has said the following: “About the case of a man who buys food then sells it before receiving delivery, he (the Imam) said, ‘It is not harmful.’ ‘Can he appoint the second buyer as his agent to receive delivery?’ He (the Imam) said, ‘It is not harmful.’”
