Protects his trust...

Protects his trust, visits him during his sickness, be present when he dies, responds to his call, accepts his gift, rewards him for keeping in touch with him, thanks him when he bestows a blessing upon him, supports him very well, safeguards his lawful possessions, performs his errands, responds to his request, seeks Allāh's mercy for him when he sneezes, guides him when he strays, responds to his greeting, finds his speech to be good, expresses appreciation for his bounties, believes him when he swears, befriends him and not antagonize him, supports him when he is an oppressor or when he oppresses: As regarding supporting him when oppresses, he keeps him away from oppressing.

As regarding supporting him when he is oppressed, he helps him take what belongs to him. He does not hand him over [to his enemy], nor does he betray him; he loves for him the same goodness which he loves for himself, and he hates the same evil to afflict him as he hates it for himself" ( Kanz al-Fawāid , Vol. 1, p. 306).

Then the Imām (ع) said, "I have heard the Messenger of Allāh (ص) saying, 'Some of you leaves out something which he owes his brother, and on the Day of Judgment, he will be tried on its account'" ( Kanz al-Fawāid , Vol. 1, p. 307). Atonement For Backbiting Be informed that it is mandatory on the backbiter to repent, regret and feel sorry for what he has done so he may get himself out of Allāh Almighty exacting on him what he deserves.

After that, he must seek forgiveness of the person whom he had backbitten, perhaps he will forgive him and get him out of his wrongdoing. He ought to seek his forgiveness while he is sorrowful, regretful about what he had done, for a pretentious person may seek forgiveness just to feign piety while inwardly he is not regretful at all, thus he adds another sin.

There are two traditions regarding its atonement: One is this tradition by the Prophet (ص): "The atonement for the one whom you had backbitten is that you seek Allāh's forgiveness for him" ( Ihyā al-Ulūm , Vol. 3, p. 145; also see Al-Kāfi , Vol. 2, p. 357 and p. 172 of Al-A`māli by Sheikh al-Mufīd).

Another is his (ص) statement: "If one owes his [Muslim or human] brother for having wronged him, whether it may be with regard to his honor or wealth, he must seek his forgiveness for it before a Day comes when there is neither a dinar nor a dirham. It will be taken out of his good deeds.
