"The right of your brother is that you know that he is your hand, your might, and your strength. Take him not as a weapon with which to disobey Allah, nor as equipment with which to wrong Allah's creatures. Do not neglect to help him against his enemy or to give him good counsel. If he obeys Allah, well and good, but if not, you should honor Allah more than him." As for the brother, he is his brother's hand, his might, and his strength. He is his support during afflictions and hardships. The Ima`m, peace be on him, has mentioned the rights of the brother as follows: A. You should not take you brother as a weapon with which you disobey Allah. B. You should not ask him for help to wrong the people and to aggress against them without any right. C. You should not neglect to help him against himself; you should guide him to the way of good and show him the path to guidance. D. You should help him against his enemy, Satan; you should warn your brother against him, frighten your brother with Allah's punishment, lest Satan should delude him and turn him away from the straight path. E. You should not neglect to give him good counsel concerning the affairs of this world and the next. If he obeys Allah, well and good, but if not, you should honor Allah more than him. source: http://www.imamreza.net/eng/imamreza.php?id=842
