CHAPTER: EXCELLENCE OF OBSERVING TWO RAK'AHS BEFORE THE EVENING PRAYER
Mukhtar b. Fulful said: I asked Anas b. Malik about the voluntary prayers after the afternoon prayer, and he replied: 'Umar struck hit hands on prayer observed after the 'Asr prayer and we used to observe two rak'ahs after the sun set before the evening prayer during the time of the Prophet of Allaah (sallAllaahu alayhi wa sallam). I said to him: Did the Messenger of Allaah (sallAllaahu alayhi wa sallam) observe them? He said: He saw us observing them, but he neither commanded us nor forbade us to do so.
Anas b. Malik reported: When we were in Medina, the moment the Mu'adhdhin made the call to the sunset prayer, the people hastened to the pillars of the mosque and prayed two rak'ahs with the result that any stranger coming into the mosque would think that the obligatory prayer had been observed owing to the number who were praying then.
Abdullah b. Mughaffal reported Allaah's Messenger (sallAllaahu alayhi wa sallam) u saying: There Is between the two calls (Adhan and Iqama) a prayer. And he mentioned it three times, and at the third time he said: This applies to those who wish to do it.
This hadith has been narrated by Abdullah b. Mughaffal by another chain of transmitters, but with this variation that he (the Prophet) said at the fourth time:" He who wishes (may do to)."
