Is the Mut'ah (consolation gift) obligatory for a wife divorced after consummation when the dower (Mahr) was specified?

Primary text

The apparent position of the Madhhab (Hanbali school, as stated by Abu Hanifa) is that the Mut'ah is not obligatory for a wife divorced after consummation, whether the dower was specified (Musaammat) or the divorce was by delegation where the dower was fixed (Mufawwada mafrood laha). Imam Ahmad stipulated that the Mut'ah is obligatory only for one for whom no dower was specified. If a dower was specified, he does not obligate the Mut'ah but recommends it (mustahabb). The recommendation stems from the general implication of the text concerning Mut'ah and its indication regarding obligation, and aligns with the view of Ali (may Allah be pleased with him) and the scholars previously mentioned.
