On Friday, an anti-terrorism court in eastern Pakistan sentenced Nadeem James, a 35-year-old Christian, to death on blasphemy charges. James, a tailor by profession, was accused by a friend of sharing "blasphemous messages" on WhatsApp's text messaging service.

Blasphemy is a highly sensitive topic in the Islamic Republic of Pakistan, where around 97 percent of its 180 million inhabitants are Muslim. Rights advocates have long been demanding a reform of the controversial blasphemy laws, which were introduced by the Islamic military dictator General Zia-ul-Haq in the 1980s.

Activists say the laws have little to do with blasphemy and are often used to settle petty disputes and personal vendettas. Religious groups oppose any change to the blasphemy law and consider it necessary for Pakistan's Islamic identity.

Pakistan's Christians and other religious minorities complain of legal and social discrimination. In the past few years, many Christians and Hindus have been brutally murdered over unproven blasphemy allegations.

One of Pakistan's most high profile blasphemy cases is that of Asia Bibi, a Christian woman who was found guilty of committing blasphemy while working in the fields in 2009 and was sentenced to death. In 2014, her death sentence was upheld by the Lahore High Court. Amnesty International called the verdict a "grave injustice."

In one case, a young girl between the ages of 10 to 14 years with Down syndrome, was accused in August of 2012 of burning pages upon which verses of the Koran were inscribed. Rimsha Masih was taken into police custody and only released months later, when charges were dropped. The case caused an uproar in her home town and beyond and sparked riots and violence against Christians in the region. In 2013, she and her family relocated to Canada.

In 2014, a Christian couple was beaten to death for allegedly desecrating a copy of the Koran. Their bodies were subsequently burned in a brick kiln.

In an interview with DW, James' brother, Faryaad Masih, rejects blasphemy allegations against his brother and says his family has been living in constant fear since James' arrest in July 2016.

DW: You deny that your brother, Nadeem James, sent blasphemous messages through WhatsApp. Do you have any proof to substantiate your claims?

Faryaad Masih: Police say that my brothers sent blasphemous material through WhatsApp but those messages could easily have been sent by James' Muslim friends through his phone. Actually, the main complainant in the case is the one who forwarded those messages.

Why would James' friends make false allegations against him?

James has three friends who live in the Gujarat area. Their names are Shakeel, Yasir and Akram. Our neighbor's daughter, Nargis, fell in love with James although she knew that he is married with two children. His friends told him he could only marry Nargis if he converted to Islam although the girl had no problem with James' religion. My brother refused to convert to Islam, and that created a rift among friends.

How did the people in the area react after the "blasphemy" news broke?

As soon as the news spread on July 4, last year, a crowd of around 200 people surrounded our houses. James, another brother of mine and I were at work at the time. When we came to know about this, we went into hiding. The mob was ready to set our houses on fire, but police stopped them.

James surrendered after two days but our family had to move to another area for safety. It saddens me that people with whom we had lived for over 17 years became our enemies after the incident.

Are you still afraid?

After James' arrest things became quite normal. But since his death sentence, fear has swept across the Christian community in the area. We rarely venture out of our house and live in constant fear. We know that anything can happen to us.

Who is providing you legal help?

No one is helping us. Our cattle have been stolen. I ran a furniture shop with a Muslim friend who gave me only 40,000 rupees [316 euros] for furniture worth over 250,000 rupees [1,977 euros]. When I demanded more money, he started threatening me. Our neighbors don't talk to us and people in the area are reluctant to interact with us.

Do you plan to appeal James' death sentence?

We are hiring a new lawyer through a non-governmental organization. We will appeal against his conviction and pray for his release. Our previous lawyer did not defend James properly. He did not even ask the court to investigate how the blasphemous message originated.

What kinds of problems do Christians have to face in Pakistan?

James told me about a 14-year-old Christian boy in his jail who has been convicted of blasphemy. How can such a young boy commit such a thing? There is no justice for Christians in Pakistan.

What sort of help are you expecting from Pakistan's civil society over James' issue?

We are poor people. My brothers' wives have also been implicated in a false case of abetment. I am an illiterate person, so is James. He did not complete his primary education. His friends framed him. The authorities should take notice of our situation.
