Although he was given the post of qadi of Egypt in Safer 1054 (April 1644) with the favor of his father-in-law, Rumeli Kazasker Muîd Ahmed Efendi and the initiative of the grand vizier got him dismissed from his duty in the same year in Jumada al-Akhir/August.
[3] After being given the Rumeli rank on 12 Dhu al-Hijjah 1057 (8 January 1648), he became an Anatolian kazasker in Jumada al-Awwal (June) and was dismissed from his post within three months.
[6] A complaint was written on behalf of the ulema in Zilhijce 1064 (October 1654) and delivered through Sheikh-ul-Islam Ebu Said Mehmed Efendi with a request for his dismissal.
Upon the dismissal of shaykh al-Islam Kocahusamzade Abdurrahman Efendi on 9 Cemaziyelevvel 1066 (March 5, 1656) due to the Cinar Incident at Atmeydani, Memekzade was given the position of sheikh-ul-Islam because he was the most senior scholar.
[7] However, according to the sources, the soldiers protested strongly against his assignment upon the provocation of some of Hocazade Mesud Efendi's men making negative claims about Memikzade Mehmed’s knowledge and morals.
Memekzade Mehmed did not stay in Bursa for long and was appointed as the judge of Mecca and allowed to go on Hajj (pilgrimage).
