Do weak hadiths carry legal rulings?

The Shaykh : Never. They are not used, and no ruling can be derived from them; it is not possible to derive a ruling from them. However, Ibn Muflih (may Allah have mercy on him) mentioned in the chapter on congregational prayer... regarding the imam, that if a hadith is weak but not severely weak, and it indicates a ruling of command or prohibition, the command is understood as a recommendation (mustahabb) and the prohibition as something disliked (makruh). However, this is not accepted absolutely. Is that clear?

The questioner : Shaykh, if...?

The Shaykh : If...

The questioner : The reason for the revelation of the verse.

The Shaykh : Yes.
