Abu Tha'laba al-Khushani reported God’s messenger as saying, “God has made certain things binding, so do not cause them to be lost; He has prohibited certain things, so do not violate them; He has fixed certain limits, so do not transgress them; and He, without being forgetful, has said nothing about certain things, so do not search into them.” Daraqutni transmitted it.

وَعَن أبي ثَعْلَبَة الْخُشَنِي قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِنَّ اللَّهَ فَرَضَ فَرَائِضَ فَلَا تُضَيِّعُوهَا وَحَرَّمَ حُرُمَاتٍ فَلَا تَنْتَهِكُوهَا وَحَدَّ حُدُودًا فَلَا تَعْتَدُوهَا وَسَكَتَ عَنْ أَشْيَاءَ مِنْ غَيْرِ نِسْيَانٍ فَلَا تَبْحَثُوا عَنْهَا» . رَوَى الْأَحَادِيثَ الثَّلَاثَةَ الدَّارَقُطْنِيُّ
