Medina, with the majority of its ayat being revealed in Mecca (verses 1-19) and its final verse (verse 20) being revealed in Medina. In his famous “Geschichte des korans”, Theodor Nöldeke places this Sura in the First Meccan Period, with the exceptions of ayat 10, 11 and 20, which were added at a later time. There are three major textual suggestions that Q73:20 is Medinan and not Meccan. Firstly, there is a clear discrepancy in the length of ayat 1-19 and verse 20, with the first 19 verses being short and verse 20 being a paragraph in length. This is a trend through the Qur'an; verses revealed in Mecca are shorter, as Muhammad is more focused on spreading the message of Islam, and the verses revealed in Medina are longer as Muhammad attempts to outline the ideal Muslim society. Secondly, there is a change in how Allah is referenced. In the first 19 ayat, Allah refers to himself mostly as “We” and “your Lord.” In ayat 20, there is a change in voice as Allah begins to refer to himself in the third person, “He”. This grammatical shift is called an iltifat, and is used for rhetorical purposes to arouse the reader's attention. The reference to fighting, further gives credence to it being Medinan. Finally, the Arabic verses 1-19 contain an end rhyme. Verse 20 breaks this end rhyme, suggesting that it was revealed at a different time. Placement and coherence with other surahs The idea of textual relation between the verses of a chapter has been discussed under various titles such as nazm and munasabah in non-English literature and coherence, text relations, intertextuality, and unity in English literature. Hamiduddin Farahi, an Islamic scholar of the Indian subcontinent, is known for his work on the concept of nazm, or coherence, in the Quran. Fakhruddin al-Razi (died 1209 CE), Zarkashi (died 1392) and several other classical as well as contemporary Quranic scholars have contributed to the studies. This surah belongs to the last (7th) group of surahs which starts from Surah Al-Mulk (67) and runs till the end of the Quran.
