Blessed is the spot, and the house, and the place, and the city, and the heart, and the mountain, and the refuge, and the cave, and the valley, and the land, and the sea, and the island, and the meadow where mention of God hath been made, and His praise glorified.Bahá’u’lláh
طُوبَى لِمَحَلٍّ وَلِبَيْتٍ وَلِمَقَامٍ وَلِمَدِينَةٍ وَلِقَلْبٍ وَلِجَبَلٍ وَلِكَهْفٍ وَلِغَارٍ وَلِأَوْدِيَةٍ وَلِبَرٍّ وَلِبَحْرٍ وَلِجَزِيرَةٍ وَلِدَسْكِرَةٍ اِرْتَفَعَ فِيهَا ذِكْرُ اللهِ وَثَنَائُهُحضرت بهاءالله
« Blessed is the spot » is a passage from a Tablet of Baháʼuʼlláh to one of His nineteen Apostles, Mírzá ʻAlí-Muḥammad, known more commonly as Ibn-i-Aṣdaq. This iconic excerpt, first translated by Shoghi Effendi in The Advent of Divine Justice, serves as an important reminder to us that, wherever we may be, that spot will be blessed if we mention God and glorify His praise there.
In the original Arabic text, the “in” sound you hear at the end of every noun is a short vowel mark called a “kasratain.” In this context, this mark indicates that the noun is indefinite. So, rather than refer to a specific sea, land, island, and so on, Baháʼuʼlláh is saying that any sea, land, or island where the mention of God is made and His praise is glorified will be blessed.
