Somalis:

In the Somali diaspora, multiple Islamic fundraising events are held every year in cities like Birmingham, London, Toronto and Minneapolis, where Somali scholars and professionals give lectures and answer questions from the audience. The purpose of these events is usually to raise money for new schools or universities in Somalia, to help Somalis that have suffered as a consequence of floods and/or droughts, or to gather funds for the creation of new mosques like the Abuubakar-As-Saddique Mosque, which is currently undergoing construction in the Twin cities.
