Gleanings — Paragraph 443
Source (Arabic)
انشآءالله نور انصاف بتابد و عالم را از اعتساف مقدّس فرماید اگر ملوک و سلاطین که مظاهر اقتدار حقّ جلّ جلالهاند همّت نمایند و به ما ینتفع به من علی الأرض قیام فرمایند عالم را انوار آفتاب عدل اخذ نماید و منوّر سازد
Translation
If the rulers and kings of the earth, the symbols of the power of God, exalted be His glory, arise and resolve to dedicate themselves to whatever will promote the highest interests of the whole of humanity, the reign of justice will assuredly be established amongst the children of men, and the effulgence of its light will envelop the whole earth.
