Abu Tha’laba Al-Khushani reported: The Messenger of Allah, peace be upon him, said, “Indeed, Allah has made duties obligatory, so do not neglect them; and He has set limits, so do not transgress them; and He has remained silent concerning things as mercy for you, not out of forgetfulness, so do not search them out.”
[Al-Daraqutani 4/184, Hasan]
عَنْ أَبِي ثَعْلَبَةَ الْخُشَنِيِّ رَضِيَ اللَّهُ عَنْهُ عَنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ
إِنَّ اللَّهَ فَرَضَ فَرَائِضَ فَلَا تُضَيِّعُوهَا وَحَدَّ حُدُودًا
فَلَا تَعْتَدُوهَا وَحَرَّمَ أَشْيَاءَ فَلَا تَنْتَهِكُوهَا وَسَكَتَ
عَنْ أَشْيَاءَ رَحْمَةً لَكُمْ غَيْرَ نِسْيَانٍ فَلَا تَبْحَثُوا عَنْهَا
حَدِيثٌ حَسَنٌ ، رَوَاهُ الدَّارَقُطْنِيُّ وَغَيْرُهُ
