the Prophet said: "O Banu Abd Manaf! Do not prevent anyone from performing Tawaf around this House, and Salat, whichever hour it is of the night or day."  

أَنَّ النَّبِيَّ ﷺ قَالَ يَا بَنِي عَبْدِ مَنَافٍ لاَ تَمْنَعُوا أَحَدًا طَافَ بِهَذَا الْبَيْتِ وَصَلَّى أَيَّةَ سَاعَةٍ شَاءَ مِنْ لَيْلٍ أَوْ نَهَارٍ وَفِي الْبَابِ عَنِ ابْنِ عَبَّاسٍ وَأَبِي ذَرٍّ
