Sayyiduna Umar bin Khattab (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) said: "Whoever provides shade over the head of a Mujahid, Allah Almighty will grant him shade on the Day of Resurrection. Whoever provides equipment for a person fighting in the way of Allah for his jihad, he will also receive a reward similar to that person. Whoever builds a mosque in which Allah is remembered, Allah Almighty will build a house for that person in Paradise."
