al-Takwīr 81:28

Li-man shāʾa minkum an yastaqīm "For whoever among you wills to go straight."

This verse is an appositive substitute for li'l-ʿālamīn in the preceding verse. The sentence, that is, works like this:

"for all the worlds — [that is] for whoever among you wills to go straight."

The substitute does not cancel what came before it; it defines it.

What this does must be seen:

• The address is universal: the text has been sent to all the worlds.
• The benefit is conditional: the one who profits by it is the one who wills.

The two do not contradict. A door may be open to everyone, and still only those who enter get inside. The verse preserves the breadth of the opening while stating whom the benefit reaches.

مِنكُم — "among you". Min is partitive (marking off a part): not all of you, but some among you.

Root: ق-و-م. This root was treated in several places in this commentary: mustaqīm at al-Fātiḥa 1/6, iqāma at al-Baqara 2/3, qayyima at al-Bayyina 98/5. I do not repeat it here.

In summary: the sense of the root is to stand, to be set upright, to straighten, and mustaqīm says two things at once — straightness and an upright stance.

And what is to be added here is that in this place the word is a verb.

What is an attribute of the path in al-Fātiḥa becomes the person's act in al-Takwīr. What was asked for there as "guide us to the straight path" is described here as "whoever wills to go straight". The same root at two ends, as asking and as doing.

The pattern: Form X. One of the functions of this form is seeking (istaghfara — he sought forgiveness). So yastaqīm is not "he became straight"; it is "he sought to be straight, looked for it, turned towards it". The pattern itself conveys an effort.

And read together with shāʾa (willed), a doubled wanting comes out: to will and to seek. The verse describes not a single decision but a sustained orientation.
