I've taught Islamic Studies courses in college numerous times. I'm giving you some of the best sources you should read before engaging with an interested Muslim. If the Muslim is not interested, then just keep talking about what Jesus had one for you, and do not compare religions.
Seeking Allah, Finding Jesus, Nabeel Qureshi
Raymond Ibrahim: Read everything he has written
Ayaan Hirsi Ali: Read everything she has written
Destiny Disrupted: A History of the World Through Islamic Eyes – Tamim Ansary. One of the best books on this subject.
