Knowledge is a thing you can carry around with you, but you may not apply it. Some knowledge is indiscriminate, and it can be damaging. I recently found a wonderful definition of wisdom: It is that thing which results in the maximum good and the least harm.

It is part of my faith as a Muslim to try to help those who are suffering from poverty or economic or political injustice.

Ever since I became a Muslim ... I've had to deal with attempts to damage my reputation and countless insinuations seeking to cast doubt on my character and trying to connect me to causes, concepts or sayings which I do not and would never wilfully subscribe to.

You can argue with a philosopher, but you can’t argue with a good song. And I think I’ve got a few good songs.

The spiritual quest was always the predominant aspect of my life. It's always been there. But there's also an incredible passion connected to it; it's not just a dry investigative process. I have been extremely emotional about it, and that comes out in the songs.

Love heats my blood, blood spins my head, and my head falls in love.
