سَمِعْتُهُ يَقُولُ مَنِ اشْتَرَطَ شَرْطاً مُخَالِفاً لِكِتَابِ اللَّهِ فَلَا يَجُوزُ لَهُ وَ لَا يَجُوزُ عَلَى الَّذِي اشْتُرِطَ عَلَيْهِ وَ الْمُسْلِمُونَ عِنْدَ شُرُوطِهِمْ فِيمَا وَافَقَ كِتَابَ اللَّهِ عَزَّ وَ جَلَّ.
‘If one forms a stipulation against the book of Allah, it is not permissible for him as well for the other party. However, the Muslims must stand by their stipulations which agree with the book of Allah, most Majestic, most Glorious. 5 ”
