Are two Rak'ahs performed before Maghrib prayer after the call to prayer permissible?

Primary text

Two Rak'ahs before Maghrib prayer after the call to prayer are permissible. The apparent view of Ahmad is that they are permissible but not Sunnah. Evidence for their permissibility includes the narration of Anas stating they used to pray two Rak'ahs after sunset before Maghrib prayer during the time of the Messenger of Allah (peace be upon him), and the Prophet neither commanded nor forbade it. Another narration from Anas states that people in Medina would rush to the pillars upon the call for Maghrib to pray two Rak'ahs, so much so that a stranger might think the prayer had already been performed. Furthermore, the Hadith states, 'Between every two calls (Adhan) there is a prayer,' with the final utterance being 'for whomsoever wills,' indicating choice. The Prophet (peace be upon him) also commanded, 'Pray two Rak'ahs before Maghrib,' and repeated it, adding 'for whomsoever wills, lest people take it as a regular Sunnah.'
