أحمد بن يحيى
When Numan returned to Yemen at the end of February 1941, the Crown Prince Ahmad bin Yahya, whom his father the Imam appointed Governor of Ta'izz in place of Ali al-Wazir, appointed him inspector of the primary schools for the province. Numan remained in contact with al-Zubayri who continued the meetings of "al-Katiba", changing its name, however, to "Shabab al-Amr", based on the title of the reform manifesto he was writing: "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"), a title based on the Quranic expression suggesting government by the "ummah". In August al-Zubayri arrived in Ta'izz with his Programme and would later be joined by other of the "shabab" from Cairo. Before his arrival al-Zubayri had consulted with Ahmad al Muta and several associates in Sana'a and had written to Numan of his plan to present the "Barnamij" to the Imam. Numan counsel him against doing so on the ground that public support had not been sufficiently organized to risk a confrontation with the Imam.
