Sunday, 21 Rajab 1436 AH corresponding to 10 May 2015 CE, marks the launch of a week of events to commemorate the destruction of the Khilafah "Caliphate" organized by Hizb ut Tahrir / Wilayah Sudan, in the capital of Sudan, Khartoum, including other cities. It serves as a reminder to the Ummah that  since the 28^thof Rajab 1342 AH i.e. ninety-four Hijri years ago and until today it is living without a head, without the "shield", and the banner of the Messenger of Allah (saw) is dropped, and the colonial flags of the darkness states are raised, the creation of Sykes - Picot.

Political dialogues were held through out, engaging many topics and receiving a wide acceptance to the call for the Khilafah "Caliphate" on the method of the Prophethood.
