سَأَلْتُ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ أَ يَصْلُحُ أَنْ يُسْلِمَ فِي اَلطَّعَامِ عِنْدَ رَجُلٍ لَيْسَ عِنْدَهُ طَعَامٌ وَ لاَ حَيَوَانٌ إِلاَّ أَنَّهُ إِذَا جَاءَ اَلْأَجَلُ اِشْتَرَاهُ وَ أَوْفَاهُ قَالَ "إِذَا ضَمِنَهُ إِلَى أَجَلٍ مُسَمًّى فَلاَ بَأْسَ" قَالَ قُلْتُ أَ رَأَيْتَ إِنْ أَوْفَانِي بَعْضاً وَ أَخَّرَ بَعْضاً أَ يَجُوزُ ذَلِكَ قَالَ "نَعَمْ".
Hadith.3951 - Al-Nadr narrated from Abdullah ibn Sinan who said:
I asked Abu Abdullah (as): "Is it permissible to enter into a Salam contract for food with a man who does not currently possess the food or livestock, but promises to purchase it and deliver it when the due date arrives?"
Imam (as) replied: "If he guarantees it for a specified term, then there is no harm in it."
I then asked: "What if he delivers part of it and delays the rest? Is that permissible?"
Imam (as) said: "Yes."
