A Review over the traditions about reasons of the descent of the first verses of Surah al-Maarij

In Quran interpretation books and in books about Quranic sciences and reasons of descent of verses of holy Quran, we can find various reasons for a lot of verses which their documentation and content should be evaluated. This article is written to mention the reason of why Sura Maarij has been sent down. The traditions of this part are being reviewed through various aspects of documentation and the content. The result is that the narrations are weak in terms of their documentation, except for Sfyany bin Eīṇa al-Hillai from Imam Sadiq, others due to a reason or more such as: documentation, weak narrators, failing to assert the narration by an eye-witness of descent of verses, are weak. In terms of context, due to some drawbacks such as: incompatibility with the meaning of Sura, Asynchrony between story and revelation of the verses, ambiguity and discordance among the traditions following each Sura. Finally, the story of the death of Numan ibn Harith Fahri in the Ghadir incident - due to the plurality of chain of narrators and harmony with the content and state of the verses - can be accepted as the reason for the descent of the Surah al-Maarij (especially the early verses).
