Do not delve into matters that Allah has left unspecified
TABARANI 18883:
from Abū Thaʿlabah —
the Messenger of Allah ﷺ said, "Allah has decreed obligations, so do not neglect them; He has forbidden certain things, so do not violate them; He has set limits, so do not transgress them; and He has left some matters unspecified ˹intentionally˺, so do not delve into them.
الطبراني ١٨٨٨٣:
عن ابو ثعلبه —
قَالَ رَسُولُ اللهِ ﷺ «إِنَّ اللهَ فَرَضَ فَرَائِضَ فَلَا تُضَيِّعُوهَا، وَنَهَى عَنْ أَشْيَاءَ فَلَا تَنْتَهِكُوهَا، وَحَدَّ حُدُودًا فَلَا تَعْتَدُوهَا، وَغَفَلَ عَنْ أَشْيَاءَ مِنْ غَيْرِ نِسْيَانٍ فَلَا تَبْحَثُوا عَنْهَا»
