The Book of the Believer · Hadith 107 (#Ḥadīth #1)

107 - عن أبي عبد الله عليه السلام قال: من مشى لامرئ مسلم في حاجته فنصحه فيها، كتب الله له بكل خطوة حسنة، ومحى عنه سيئة، قضيت الحاجة أولم تقض، فإن لم ينصحه فقد خان الله ورسوله، وكان رسول الله صلى الله عليه وآله وسلم خصمه

107. It has been reported that Abu 'Abd Allah said: One who goes along with a Muslim to help him and counsels him accordingly, Allah will write for him, for every step (he takes), a good deed and erases from him a misdeed regardless of whether he succeeds in helping him or not. If he does not counsel him sincerely, then he has betrayed Allah and His Messenger, and it is the Messenger of Allah who will litigate against him.
