Bollywood superstar Salman Khan has time and again ensured that he promotes the work of his industry friends, be it during events or on social networking platforms. His gestures have always caught people's attention whether he tweeted the first look poster of Shah Rukh Khan's upcoming film, 'Raees' or promoted his good friend Aamir Khan's film 'Dhoom 3' (2013) on the television show he hosted. And now, he has taken to Twitter for Emraan Hashmi.

While it is known that Emraan Hashmi has penned a book on the struggle and hardships he faced when his now six-year-old son Ayaan's was detected with cancer, Salman Khan has taken extra effort to take snap shot of the book's cover page and tweeted it. The book's cover talks about a father's trials and triumphs and how it is a transformative experience of his life.
