Hat-tip goes to Zaid Benjamin for the Arabic text. Below I give my translation of Sheikh Abu Mohammed al-Jowlani's (the leader of Jabhat al-Nusra) alleged entire statement on the cancellation of the 'Islamic State of Iraq and ash-Sham' merger announced by Abu Bakr al-Baghdadi of al-Qa'ida's Iraqi branch last month. In light of Zawahiri's recent statement for unity in Jihad, this alleged message from Jowlani- with the revelation of Zawahiri's role in devising a compromise- does not contain anything all that surprising as regards content. All that said, I have nothing as of yet to verify the statement definitively.
In terms of the relationship between Jowlani and Baghdadi, if the statement is authentic, it is a mere return to the status quo prior to the rift caused by Baghdadi's announcement, in that Jowlani (as he always has done) sees Baghdadi as a brother in Jihad fighting the same enemies and allied to the same general al-Qa'ida leadership. Further, we have the same admission as in April of cooperation between Islamic State of Iraq and Jabhat al-Nusra. But pace my expectations, al-Manaarah al-Baydaa is going to make a comeback:
Translation
"In the name of God, the Compassionate, the Merciful.
Alhamduillah wa salatu wa s-salaam on the Apostle of God, his relatives, his companionship and whosoever is a supporter of him.
And following:
To the emirs and leaderships of the regions of Jabhat al-Nusra...the best brothers...salaam alaykum wa rahmat Allah wa barakaatuhu:
The disagreement which arose was no longer unknown to anyone...and indeed we had raised the matter with Sheikh Dr. Aymenn al-Zawahiri- may God protect him- so that he might make a judgment on the matter, and verily the response has come to us, wa Allah al-Hamd after the length of consideration.
Excerpt of what came in the message:
1. The cancellation of the Islamic State of Iraq and ash-Sham, while the Islamic State of Iraq remains within Iraq under the leadership of Sheikh Abu Bakr al-Baghdadi- may God protect him.
2. The continued existence of Jabhat al-Nusra under the leadership of Sheikh Abu Muhammad al-Jowlani, distinct for a base of Jihad and aligned with the general leadership [i.e. under Sheikh Aymenn al-Zawahiri].
3. The bond of protection and cooperation between Jabhat al-Nusra and Islamic State of Iraq continues.
4. The appointment of Sheikh Abu Khalid as-Souri as a representative of Sheikh Aymenn al-Zawahiri in order to apply the points of the solution provided in the message of the Sheikh (God protect him).
5. An end to the dispute and its kindling.
So I ask all my brothers in Jabhat al-Nusra to bind themselves to everything set forth in the message...especially its focus on ending the dispute, quarrel and provocation, as well as the pursuit to recover harmony and unity.
And may all know that we have all affection, respect and appreciation for the leadership of Islamic State of Iraq and for Sheikh Abu Bakr al-Baghdadi and that we will continue to be interconnected, based on affection, brotherhood and cooperation in piety and taqwa (bewaring of God), and so we are in one boat and we will confront the enemies of God together.
Allahum tabba alayna wa ighfar lana, and gather our speech on righteousness and guidance.
Further, I announce to you the good news that output from al-Manaarah al-Baydaa [Jabhat al-Nusra's official channel] will return soon if God Almighty wills. And God is the giver of success and in Him is trust.
Your brother,
Abu Muhammad al-Jowlani."
Update
While this statement was interesting to translate, my opinion finally leans against its supposed authenticity. I could not find this anywhere on jihadi forums like Ansar al-Mujahideen (and neither could my friends like Shami Witness). In short, as Aaron Zelin puts it, the supposed statement is 'pure bullshit.'
