The Book of Prayer
وَعَنْ اِبْنِ عُمَرَ - رَضِيَ اَللَّهُ عَنْهُمَا-]قَالَ] : { نَهَى اَلنَّبِيُّ - صلى الله عليه وسلم -أَنْ يُصَلَّى فِي سَبْعِ مَوَاطِنَ : اَلْمَزْبَلَةِ , وَالْمَجْزَرَةِ , وَالْمَقْبَرَةِ , وَقَارِعَةِ اَلطَّرِيقِ , وَالْحَمَّامِ , وَمَعَاطِنِ اَلْإِبِلِ , وَفَوْقَ ظَهْرِ بَيْتِ اَللَّهِ } رَوَاهُ اَلتِّرْمِذِيُّ وَضَعَّفَهُ [1] .
Narrated Ibn 'Umar (RA): Allah's Messenger (ﷺ) forbade prayer at seven places; a dump, a slaughter house, a graveyard, the middle of the path, a bathroom, and where camels sit at a watering place and on (roof) of the Ka'bah. [Reported by at-Tirmidhi who graded it Da'if (weak)].
