Engineer Osman Bakhach, Director of the Central Media Office of Hizb ut Tahrir gave a speech via Skype under the title, "Role of the Scholars in the Establishment of the Khilafah "Caliphate"" that was held in Jakarta, Indonesia on Tuesday, 18 Dhu al-Qi'dah 1434 AH corresponding to 24 September 2013 CE.

"Al-Wujood" and "Al-Abyadh" have been mentioned, but the term "Al-Wujood" was explained by an example and it was repeated afterwards. But no example of "Al-Abyadh" was given. "Istighna" and "Iftiqar" were mentioned in a way that confused me. How can we understand the phrase above in a clearer way?
