Gleanings — Paragraph 698
Source (Arabic)
إنّ الّذین هاجروا من أوطانهم لتبلیغ الأمر یؤیّدهم الرّوح الأمین ویخرج معهم قبیل من الملائکة من لدن عزیز علیم طوبی لمن فاز بخدمة الله لعمري لا یقابله عمل من الأعمال إلّا ما شآء ربّک المقتدر القدیر إنّه لسیّد الأعمال وطرازها کذلک قدّر من لدن منزل قدیم من أراد التّبلیغ ینبغي له أن ینق
Translation
They that have forsaken their country for the purpose of teaching Our Cause — these shall the Faithful Spirit strengthen through its power. A company of Our chosen angels shall go forth with them, as bidden by Him Who is the Almighty, the All-Wise. How great the blessedness that awaiteth him that hath attained the honor of serving the Almighty! By My life! No act, however great, can compare with it, except such deeds as have been ordained by God, the All-Powerful, the Most Mighty. Such a service is, indeed, the prince of all goodly deeds, and the ornament of every goodly act. Thus hath it been ordained by Him Who is the Sovereign Revealer, the Ancient of Days.
