Consistency in Reciting al-Mufassal in the Maghrib Prayer

Question:
He says: Honorable Shaykh, may Allah grant you success, is it a recommended practice (sunnah) to consistently recite al-Mufassal in the Maghrib prayer, given that Ibn al-Qayyim (may Allah have mercy on him) disputes the recommendation of doing so in Zād al-Ma‘ād?

Answer:
I have not heard him dispute this, but he says that one does not always restrict oneself to this; sometimes it is this and sometimes it is that. He does not dispute this point, but the Messenger (peace and blessings be upon him) said: He said to Mu'adh: So he does not dispute this, but he says that one does not always restrict oneself to this and make it a constant habit; sometimes one recites something else. Yes.
