Muslim Aid, the international relief and development agency, has promoted Hamid Azad, its deputy chief executive, to lead the organisation.
He replaces Syed Sharfuddin who has retired after being chief executive since 2010 of the charity, which has an annual income of £25m.
Azad joined the charity in 2005 as a consultant on its tsunami response programmes and became head of overseas programmes in 2006. He has been deputy chief executive for four years. He was previously head of community and international programmes at the multi-faith charity Faith Regen UK.
In a statement, Azad said he felt humbled to take on the role. "I love Muslim Aid and I have always been passionate about its amazing mission and vision," he said.
Dr Manazir Ahsan, chair of Muslim Aid, said Azad would bring "a rich experience of the development sector and a wealth of knowledge and talent in developing and implementing relief and development programmes".
The charity has also appointed Shuaib Yusaf as assistant chief executive. He was previously general manager at the Muslim charity Al-Khair Foundation.
