"The Prophet prohibited Salat from being performed in seven places: the dung heap, the slaughtering area, the graveyard, the commonly used road, the wash area, in the area that camels rest at, and above the House of Allah (the Ka'bah)."  

أَنَّ رَسُولَ اللَّهِ ﷺ نَهَى أَنْ يُصَلَّى فِي سَبْعَةِ مَوَاطِنَ فِي الْمَزْبَلَةِ وَالْمَجْزَرَةِ وَالْمَقْبُرَةِ وَقَارِعَةِ الطَّرِيقِ وَفِي الْحَمَّامِ وَفِي مَعَاطِنِ الإِبِلِ وَفَوْقَ ظَهْرِ بَيْتِ اللَّهِ  

(Another chain with a similar narration)  

عَنِ النَّبِيِّ ﷺ نَحْوَهُ بِمَعْنَاهُ قَالَ وَفِي الْبَابِ عَنْ أَبِي مَرْثَدٍ وَجَابِرٍ وَأَنَسٍ أَبُو مَرْثَدٍ اسْمُهُ كَنَّازُ بْنُ حُصَيْنٍ
