السيوطي:٢-٣٢١٢b

"عن مُحَارِبِ بْنِ دِثَارٍ: أَنَّ عُمَرَ بْنَ الْخَطَّابِ قَالَ لِرَجُلٍ قَاضٍ بِدِمَشْق: كَيْفَ تَقْضى؟ قَالَ: بِكِتَابِ اللَّهِ، قَالَ: فَإِذَا جَاءَكَ مَا لَيْسَ فِى كِتَابِ اللَّه؟ قَالَ: أَقْضِى بسُنَّةِ رَسُولِ اللَّهِ، قَالَ: فَإِذَا جَاءَ مَا لَيْس فِيهِ سُنَّةٌ عَنْ رَسُولِ اللَّهِ؟ قَالَ: اجتَهدُ بِرَأْيى وَأُؤَامِرُ جُلَسَائِى، قَالَ: أَحْسَنْتَ".
