It is narrated from Sayyiduna Umar (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever provides shade over a Mujahid, Allah will provide shade over him on the Day of Resurrection. Whoever equips a Mujahid with the necessities of Jihad until he is able to stand on his own feet, a reward equal to that of the Mujahid will continue to be written for him. And whoever builds a mosque for the pleasure of Allah in which Allah is remembered, Allah will build a house for him in Paradise."
