On December 31, 2010, Hamid posted a series of letters online, introducing them as "five articles, full of frankness and ardor, sent to me by one of the brothers in jihad, an old comrade in arms from Afghanistan." These are thought to have been written by the al Qaeda commander Saif al-Adel. The letters discuss the current jihad in Afghanistan, contain constructive criticisms of the Mujahideen and Islamic Scholars and argue that the Jihadist movement needs to acknowledge and learn from its mistakes.[8] An additional five letters, allegedly from Saif al-Adel, were posted on 23 March 2011,[9][better source needed][10] covering the Arab Spring uprisings.
