A growing social media conversation in Arabic is calling for the implementation of Sharia, or Islamic law, to be abandoned.
Discussing religious law is a sensitive topic in many Muslim countries. But on Twitter, a hashtag which translates as "why we reject implementing Sharia" has been used 5,000 times in 24 hours. The conversation is mainly taking place in Saudi Arabia and Egypt. The debate is about whether religious law is suitable for the needs of Arab countries and modern legal systems.
Dr Alyaa Gad, an Egyptian doctor living in Switzerland, started the hashtag. "I have nothing against religion," she tells BBC Trending, but says she is against "using it as a political system". Islamists often call for legal systems to be reformed to be consistent with Sharia principles, and some want harsh interpretations of criminal punishments to be implemented. Dr Gad says she is worried about young people adopting the extremes of this kind of thinking. "You see it everywhere now, Islamic State is spreading mentally as well as physically" she told BBC Trending.
One of Dr Gad's tweets compared what action is taken against those who commit crimes under strict interpretations of Sharia to those who do so in Western societies.
The Tweet says: "A thief under Sharia rule has his hand cut off and becomes a burden on society - and a Norwegian criminal is rehabilitated to become a good citizen"
