Apple has taken down one of the world's most popular Koran apps in China, following a request from officials, APA reports citing BBC.
Quran Majeed is available across the world on the App Store - and has nearly 150,000 reviews. It is used by millions of Muslims.
The BBC understands that the app was removed for hosting illegal religious texts.
The Chinese government has not responded to the BBC's request for comment.
The deletion of the app was first noticed by Apple Censorship - a website that monitors apps on Apple's App Store globally.
In a statement from the app's maker, PDMS, the company said: "According to Apple, our app Quran Majeed has been removed from the China App Store because it includes content that is illegal."
"We are trying to get in touch with the Cyberspace Administration of China and relevant Chinese authorities to get this issue resolved".
The company said it had close to one million users in China.
The Chinese Communist Party officially recognises Islam as a religion in the country.
