“How lovely is your dwelling place, Lord Almighty! My soul yearns, even faints, for the courts of the Lord; my heart and my flesh cry out for the living God. Even the sparrow has found a home, and the swallow a nest for herself, where she may have her young— a place near your altar, Lord Almighty, my King and my God. Blessed are those who dwell in your house; they are ever praising you (selah). Blessed are those whose strength is in you, whose hearts are set on pilgrimage. As they pass through the Valley of Baka, they make it a place of springs; the autumn rains also cover it with pools. They go from strength to strength, till each appears before God in Zion. Hear my prayer (selah), Lord God Almighty; listen to me, God of Jacob.”
Psalm 84:1-8 NIV
The NIV scholars rendered Salaah as selah in the NIV bible as a footnote. Clearly here we have mention of people always doing Salaah at the 'house of the Lord'.
Allah knows best!
Holy Quran 3:96
إِنَّ أَوَّلَ بَيْتٍ وُضِعَ لِلنَّاسِ لَلَّذِي بِبَكَّةَ مُبَارَكًا وَهُدًى لِّلْعَالَمِينَ
The first house established for mankind is the one at Bekka; blessed, and guidance for all people.
Holy Quran 3:97
فِيهِ آيَاتٌ بَيِّنَاتٌ مَّقَامُ إِبْرَاهِيمَ ۖ وَمَن دَخَلَهُ كَانَ آمِنًا ۗ وَلِلَّهِ عَلَى النَّاسِ حِجُّ الْبَيْتِ مَنِ اسْتَطَاعَ إِلَيْهِ سَبِيلًا ۚ وَمَن كَفَرَ فَإِنَّ اللَّهَ غَنِيٌّ عَنِ الْعَالَمِينَ
In it are evident signs; the Station of Abraham. Whoever enters it attains security. Pilgrimage to the House is a duty to God for all who can make the journey. But as for those who refuse—God is Independent of the worlds.
I will add this data to the Salaah document and to the Hajj document inshallah.
