Muwatta Malik #429
Shortening the Prayer
The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
وَحَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ عُمَرَ بْنَ الْخَطَّابِ، بَنَى رَحْبَةً فِي نَاحِيَةِ الْمَسْجِدِ تُسَمَّى الْبُطَيْحَاءَ وَقَالَ مَنْ كَانَ يُرِيدُ أَنْ يَلْغَطَ أَوْ يُنْشِدَ شِعْرًا أَوْ يَرْفَعَ صَوْتَهُ فَلْيَخْرُجْ إِلَى هَذِهِ الرَّحْبَةِ .
Yahya related to me from Malik that he had heard that Umar ibn
al-Khattab set aside an area near the mosque called al-Butayha and
said, "Whoever wishes to talk nonsense or recite poetry or raise his
voice should go to that area."
