The Messenger of Allah ﷺ having said: Allah, Most High, says: "I make a third with two partners as long as one of them does not cheat the other, but when he cheats him, I depart from them."  

إِنَّ اللَّهَ يَقُولُ أَنَا ثَالِثُ الشَّرِيكَيْنِ مَا لَمْ يَخُنْ أَحَدُهُمَا صَاحِبَهُ فَإِذَا خَانَهُ خَرَجْتُ مِنْ بَيْنِهِمَا
