Narrated by Sayyiduna Abdullah bin Umar (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Whoever seeks refuge with you by the name of Allah, grant him refuge. Whoever asks you by the name of Allah, give him what he asks. Whoever invites you, accept his invitation. And whoever does good to you, repay him; and if you do not have anything to repay him with, then pray for him so much that you feel you have repaid him.
