From the route of Abu Tha^labah al-Khushaniyy Jurthum bin Nashir, may Allah accept his deeds, from the Messenger of Allah , sallallahu ^alayhi wa sallam, who said:
<<Allah , the Exalted, decreed obligatory matters so do not waste them, and set parameters so do not violate them, and decreed unlawful matters so do not commit them, and left matters unmentioned about—unforgetful– as a mercy to you so do not fetch them.>>
This Hadith is Hasan and narrated by ad-Daraqutniyy and others.
