`Sayyiduna Abdullah Muzani (may Allah be pleased with him) narrates from the Noble Prophet (peace and blessings be upon him) that he (peace be upon him) said: "Perform voluntary prayers before the Maghrib prayer." (He said this three times) and the third time he said: "Whoever wishes." He (peace be upon him) did not like that people should consider this as Sunnah (therefore, he gave the choice that whoever wishes may perform it and whoever wishes may leave it).
