It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) concerning this statement of Allah Almighty: "He has given permission to those who fight, because they were wronged; and indeed, Allah is able to give them victory" [Surah al-Hajj: 39] , that he recited it (in this way) and said: "This is the very first verse revealed concerning fighting (jihad)." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.
