Hossam, take a bow. These are magnificent and you should be proud of your collection.
I checked out a source site and found an artist statement from the man himself:
Art is my way of expressing my concepts & perspectives in life. Life is full of images; through my art I try to capture the essence of those images on canvas.
Abstract is my keyword. Nature is my inspiration. Mind, shapes, and imaginations are my basic elements.
My digital art explores the magic of our heritage in a new contemporary vision & give ‘rebirth’ to old & traditional icons; with the genuine use of colors, calligraphy, icons, & patterns.
Through my artwork I try to bring to life the beauty of old times, the depth of memorable images in a modern unique vision. Thus text & calligraphy are features that I use. The strong impact of words merged with the patterns make the piece of art a true illustration of my perspectives.
