A group of Muslim men hit the streets to help their neighbors after a tropical storm Harvey broke in Texas with devastating floods.

Over 100 members of Muslim Youth USA, and 40 members of the Ahmadiyya Muslim Youth Association, gave out foods, water and other supplies in Houston, the organizers said.

Both groups expect to attract more volunteers from surrounding cities when the roadways open up.

Madeel Abdullah, director of humanitarian affairs for the Ahmadiyya Muslim Youth Association, said over 700 members of the organization have been affected by the recent storm.

He noted that the volunteers are helping anybody else that’s in distress.

“We’ve already provided basic supplies such as food items and water bottles,” Abdullah said, “and we have a few members who have boats who are going around making sure everyone is safe.”

The groups were supported by Humanity First, an Ahmadiyya Muslim charity that is dedicated to disaster relief.

Qasim Rashid, Ahmadiyya Muslim Community spokesman, said the groups had mobilized both their local and national chapters before the storm.

They began dispatching volunteers into Houston neighborhoods as early as Sunday – just two days after the storm first began.

“Whenever your fellow Americans are in need, you need to be the first ones on the ground to help them,” Rashid said.
