The Afghani cleric Sadschad Mohsini, holding a smartphone, sits on a rug in his home in Bamian, Afghanistan, 24 October 2014. Mohsini finds that social media is a useful tool to spread faith. In 2008 he caused an uproar after photos of him shaking the hand of the wife of then US President, Laura Bush, were shared around the world. Today the 67-year old uses social media to advise young people in matters of faith and religion. His son taught him how to navigate search engines and explained how Facebook works.
