"You were my partner during the Ignorance period and you were the best of partners, you did not contend or dispute."  

لِلنَّبِيِّ ﷺ كُنْتَ شَرِيكِي فِي الْجَاهِلِيَّةِ فَكُنْتَ خَيْرَ شَرِيكٍ كُنْتَ لاَ تُدَارِينِي وَكُنْتَ لاَ تُمَارِينِي  

"Sa'd, 'Ammar and I entered into a partnership on the day of Badr, (agreeing to share) whatever was allotted to us. 'Ammar and I did not get anything, but Sa'd got two men (slaves)."  

اشْتَرَكْتُ أَنَا وَسَعْدٌ وَعَمَّارٌ يَوْمَ بَدْرٍ فِيمَا نُصِيبُ فَلَمْ أَجِئْ أَنَا وَلاَ عَمَّارٌ بِشَىْءٍ وَجَاءَ سَعْدٌ بِرَجُلَيْنِ  

"The Messenger of Allah ﷺ said: 'There are three things in which there is blessing: A sale with deferred payment; Muqaradhah (profit sharing); and mixing wheat with barley for one's house, but not for sale."'  

قَالَ رَسُولُ اللَّهِ ﷺ ثَلاَثٌ فِيهِنَّ الْبَرَكَةُ الْبَيْعُ إِلَى أَجَلٍ وَالْمُقَارَضَةُ وَإِخْلاَطُ الْبُرِّ بِالشَّعِيرِ لِلْبَيْتِ لاَ لِلْبَيْعِ
