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.
"Indeed, Allah Almighty has enjoined obligations, so do not violate them; He has set limits, so do not transgress them; He has forbidden things, so do not commit them; and He has kept silent about things out of mercy for you, not out of forgetfulness, so do not search for them."
"إن الله تعالى فرض فرائض فلا تضيعوها، وحد حدوداً فلا تعتدوها، وحرم أشياء فلا تنتهكوها، وسكت عن أشياء رحمة لكم غير نسيان فلا تبحثوا عنها"
