(27) Chapter: Reverence towards the Sanctity of the Muslims

Al-Bara' bin 'Azib (May Allah bepleased with them) reported:
The Prophet (ﷺ) commanded us to observe seven things and forbade us seven. He ordered us to visit the sick; to follow funeral processions; to respond to a sneezer with 'Yarhamuk-Allah (May Allah have mercy on you)' when he says 'Al-hamdu lillah (Praise be to Allah),' to help the oppressed and to help others to fulfill their oaths, to accept invitation and to promote greeting. He forbade us to wear gold rings, to drink in silver utensils, to use Mayathir (silk carpets placed on saddles), to wear Al-Qassiy (a kind of silk cloth) to wear fine silk brocade.

[Al-Bukhari and Muslim].

Commentary: To materialize the pledge means that if a person relies on you and says that by Allah, you must do such and such a thing, then you should not let him down, you should do that work and fulfill his pledge. But this is subject to the condition that the work in question is not unlawful. It is not only permissible but also comes in the list of high moral values.
