Surah 20. Ta-Ha, Ayah 124

I.e., sterile and spiritually narrow, without any real meaning or purpose: and this. as is indicated in the subsequent clause, will be a source of their suffering in the hereafter.

 The Reminder is another name for the Quran.

Again, as in the last two verses, there is a variation from the previous passage (ii. 39). The consequences of the rejection of Allah's guidance are here expressed more individually: a life narrowed down, and a blindness that will persist beyond this life. "A life narrowed down" has many implications: (1) it is a life from which all the beneficent influences of Allah's wide world are excluded; (2) in looking exclusively to the "good things" of this life, it misses the true Reality.
