Ahmad bin Yahya
Numan returned to Yemen in February 1941 and was given the office of inspector of primary schools for the Province of Ta'izz by the Crown Prince Ahmad bin Yahya, who was governor at the time. Zubayri remained in Cairo where he continued the discussion group, which he renamed "Shabab al-Amr". In addition he wrote a manifesto designed to persuade Imam Yahya the benefits of reform by using Islamic arguments: "al-Barnamij al-Awwal min Baramij Shabab al-Amr bi'l-Ma'ruf wa 'l-Nahi 'an al-Mankur" ("The First Programme of the Youths for Promoting the Good and Preventing the Bad"). The manifesto, heavily influenced by the Muslim Brotherhood movement in Egypt, had four general goals: (i) return to a pure spirit of Islam; (ii) expansion of education; (iii) economic reforms; and (iv) stronger ties with other Muslim states.
