Mohammad Shafi, an Imam, and his son Mohammad Aslam were fined and sentenced to life in prison for removing a poster about an event celebrating the Prophet Muhammad's birthday.
In April 2010, after taking down a poster promoting a local religious event celebrating the birthday of the Prophet Muhammad, which allegedly had text from the Qur’an written on it, imam Mohammad Shafi and his son Mohammad Aslam were arrested on charges of blasphemy. The poster had been put up outside a grocery store they operated, and they were also accused of “trampling” it after taking it down.
After several months in detention, the two were finally sentenced to life imprisonment for insulting the Prophet Muhammad in January 2011.
“Shafi is a practising Muslim. He is the imam of a mosque and he had recently returned from a pilgrimage to Saudi Arabia … I am defending them because I am convinced they are not guilty of blasphemy.” - Arif Gurmani, legal counsel for the two men

Pakistan is one of the most repressive countries in the world with regard to freedom of expression, including and especially religious freedom. Blasphemy (i.e. insults) against religion in general can result in imprisonment, while blasphemy against Islam carries the much harsher punishment of death. Both in terms of the aggressiveness with which the Islamic-conservative government prosecutes such cases, as well as the harshness of punishment, Pakistan remains one of the worst places on the planet to speak out against religion or religious fundamentalism.
