Nabeel Qureshi grew up in a devout Muslim in the United States.
He had read the entire Quran by the time he was 6 and prayed five times a day without fail.
His devotion to Islam didn't waver.
Then in college he and a Christian friend debated historical claims of both religions.
After three years, Qureshi realized that the Gospel could withstand rigorous scrutiny and Islam could not.
In his book, Seeking Allah, Finding Jesus, Qureshi describes his dramatic quest to defend Islam and what it cost him when he discovered the truth.
