As the significance of the subject of the talk required its affirmation on the event of Hajj Muhammad dispatched Ali to follow Abu Bakr, who had just left for Makkah to lead the Pilgrims to the Ka'abah. He trained Ali to convey the talk before the representatives of the various clans of Arabia in order to advise them regarding the new policy guidelines pertinent to the mushriks. Starting from ayat 38 up to 72nd ayat the subsequent talk was revealed during Rajab A.H. 9 or a little before this, when Muhammad was occupied with getting ready for the Campaign of Tabuk. The Believers were encouraged to take a dynamic part in Jihad, and the shirkers were seriously reproached for keeping down their riches and for wavering to forfeit their lives in the path for Allah due to their hypocrisy, powerless belief(iman) or carelessness. The final section of ayaat 73rd to last, was uncovered on his return from the Campaign of Tabuk. There are a few pieces revealed in different events during the same time frame and were incorporated by Muhammad into the Surah as per instructions from Allah. This talk cautions the hypocrites of their malevolent deeds and censures those Believers who had remained behind in the Campaign of Tabuk. At that point in the wake of berating them, Allah exculpates those genuine Believers who had not partaken in the Jihad in the Way of Allah for one explanation or the other. According to Zayd ibn Thabit, when the Qu'ran was first being compiled, he found the last verses of this Surah in the possession of Abu al-h al-Ansari and no one else. In another account, Ubay ibn Ka'b informed Zayd that Muhammad taught him the end of this "sūrah" and recited the same verses. Some, like Ibn Hazm, suggested that Abu Khuzayma was the only one to have the last verses in written form, as Zayd and others had memorized them. In a continuum of Surah Al-Anfal, this Surah additionally manages the issues of harmony and war and puts together the subject with respect to the Tabuk Expedition.The Significant Issues, Divine Laws and pieces of Guidance incorporated in this surah are as follows   is termed as the "Sword Verse". The journalist Arun Shourie has criticized this and many other verses from the Quran contending that the Sunnah and the Hadith are equally evocative in their support of Jihad.
