Chapter 96: Holding Fast to the Qur'an and Sunnah
Narrated 'Abdullah Al Muzam: The Prophet (ﷺ) said, "Perform (an optional) prayer before Maghrib prayer." (He repeated it thrice) and
the third time he said, "Whoever wants to offer it can do so," lest the people should take it as a Sunna
(tradition). (See Hadith No. 277, Vol. 2)
