وَعَنِ الْمُخْتَارِ بْنِ فُلْفُلٍ قَالَ: سَأَلْتُ أَنَسَ بْنَ مَالِكٍ عَنِ التَّطَوُّعِ بَعْدَ الْعَصْرِ فَقَالَ: كَانَ عُمَرُ يَضْرِبُ الْأَيْدِيَ عَلَى صَلَاةٍ بَعْدَ الْعَصْرِ وَكُنَّا نُصْلِي عَلَى عَهْدِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ رَكْعَتَيْنِ بَعْدَ غُرُوبِ الشَّمْس قبل صَلَاةِ الْمَغْرِبِ فَقُلْتُ لَهُ: أَكَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُصَلِّيهِمَا؟ قَالَ: كَانَ يَرَانَا نُصَلِّيهِمَا فَلَمْ يَأْمُرْنَا وَلَمْ يَنْهَنَا. رَوَاهُ مُسلم

Al-Mukhtar ibn Fulful said: I asked Anas ibn Malik about voluntary prayers after the afternoon prayer. He replied: Umar used to strike hands to stop prayer after the afternoon prayer, but during the time of the Messenger of God, peace and blessings be upon him, we used to pray two rakahs after sunset and before the sunset prayer. I asked him: Did the Messenger of God pray them? He said: He saw us praying them, but neither commanded us nor forbade us. Muslim transmitted it.
