1. Ali ibn Ibrahim has narrated from his father from ibn abu ‘ Umayr from Jamil ibn Darraj who has said the following: “Abu ‘ Abd Allah, ‘Alayhi al-Salam, has said, ‘Advance payment to receive goods at an appointed time in the future is lawful if the length and width are fully described.”’
Isnādعَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ جَمِيلِ بْنِ دَرَّاجٍ عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام)
لا بَأْسَ بِالسَّلَمِ فِي الْمَتَاعِ إِذَا وَصَفْتَ الطُّولَ وَالْعَرْضَ.
