The Makkansuras are the chronologically earlier suras of the Qur'an that were revealed at Makka. They are typically shorter, with relatively short ayat, and mostly come near the end of the Qur'an. Most of the suras containing Muqatta'at are Makkan.
Other verses of the Sura mostly resemble, from the point of tone, the MeccanSuras, whose short and meaningful verses warn of the Resurrection and the horrible events of the Hereafter.
Particularly, the last verses of the Sura, which speak about the mockings of the disbelievers at the believers, match the earlier environment of Mecca where Muslims were in a minority and unbelievers were in a majority.
Perhaps, it is for this reason that some commentators consider a part of the SuraMeccan and another part of it belonging to the Medina period.
As the Medinian suras are generally the longer ones the order is not chronological; and the difficulty of rearranging them in chronological order is increased by the fact that most of the Medinian and many of the Meccansuras are composite, containing discourses or different periods bound up together.
In the suras of this period old themes are repeated again and again; the general tone is sombre, and there are passages of anxious and heart-searching meditation.
But the Meccansuras mention only morning and evening prayers and private prayer during the night; indeed, the Quran nowhere explicitly prescribes the five daily prayers nor the ritual of prostration.
