Musnad Abu Ya'la al-Mawsili 228:2

'Abd al-Rahman ibn Salih al-Azdi narrated to us, 'Ali ibn Mushir narrated to us, from 'Abd al-'Aziz ibn 'Umar ibn 'Abd al-'Aziz, from 'Abd Allah ibn Mawhab, from Tamim al-Dari, who said: I asked the Prophet, peace and blessings of Allah be upon him, about a man who embraces Islam at the hands of a man. He said: "He is the most entitled of people to his life and his death."
