al-Anbiyāʾ 21:105-106

Wa laqad katabnā fi'z-zabūri min baʿdi'dh-dhikri anna'l-arḍa yarithuhā ʿibādiya'ṣ-ṣāliḥūn · Inna fī hādhā la-balāghan li-qawmin ʿābidīn

"Indeed We wrote in the Psalter, after the Remembrance, that the earth would be inherited by My righteous servants. · In this there is a sufficient message for a people who serve."

Zabūr — root ز-ب-ر. The root was treated at al-Qamar and at Fāṭir. The sense of the root: to write, to incise in stone; zabara'l-kitāb — he wrote the book. Zubur — written pages. The word conveys writing that has been incised to last.

And there is disagreement about what the two words correspond to:

I transmit the disagreement and do not impose a preference. Differences are transmitted in the reading of the two words as well (al-Zabūr / al-Zubur); I name no reciter.

And this expression is directly connected with the sūra's series of prophets. The fact belongs entirely to the text.

Across the series the same word had been repeated:

Four occurrences; three in the series, the fourth outside it.

I record this as my own reading, its ground being the count above: the attribute the sūra used three times in the series is made, at the end, the subject of a promise. That is, the promise is tied not to a community but to the quality described in the series.

And I enter a note per the method (Method): the verse does not set up a promise of property to an ethnic or a religious group. The condition is in the verse's own wording: ʿibādī (My servants) and al-ṣāliḥūn (the righteous). Whoever carries that quality is included in it.

بَلَٰغ — root ب-ل-غ: to reach a place, to arrive. And the word is used in two senses: tablīgh (conveying) and "what is enough" (balāgh — provision that suffices). The second sense gives the sentence the tone of "this much is enough".

لِّقَوْمٍ عَٰبِدِينَ — and the word ʿābidīn for the third time in the sūra: 73 (wa kānū lanā ʿābidīn), 84 (dhikrā li'l-ʿābidīn), 106 (li-qawmin ʿābidīn). It is a countable fact.
