موطأ مالك#1387HasanThese are the words of a Companion, not of the Prophet ﷺ. The chain is graded on its own terms.
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
