Muwatta Malik · Hadith 1387
وَحَدَّثَنِي مَالِكٌ، عَنِ الْعَلاَءِ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، أَنَّ عُثْمَانَ بْنَ عَفَّانَ، أَعْطَاهُ مَالاً قِرَاضًا يَعْمَلُ فِيهِ عَلَى أَنَّ الرِّبْحَ بَيْنَهُمَا .
Malik related to me from al-Ala ibn Abd ar-Rahman from his father from his father that Uthman ibn Affan gave him some money as qirad to use provided the profit was shared between them
