The Islamic month of fasting began on Monday and runs until the fourth of June.
Christian charity Interserve is calling on believers to pray for the protection of the Muslim community and that they would come to know Jesus.
In a statement, it said: "When reading stories in the news, like that of the tragic shootings at the Mosque in Christchurch, New Zealand, it is very easy to feel numb and hopeless.
"Sadly since that dark day on 15 March there has been a rise in Anti Muslim hate Crimes in the UK.
"Inaction is clearly not the answer; a response is needed, a raising up of prayer. If we do not pray then prejudice will gain power, fear will fester and relationships built across divides will die."
The charity is encouraging Christians to download a prayer guide which over a million people around the world are expected to use across 37 languages.
