As for bodings of good, these used to please the Prophet (SAW) and so when he heard good words from someone, he used to say: "We have taken from you a good portent from your mouth," Abu Dawud, Ahmad. See also Al-Albani, Silsilatul-'Ahadith As-Sahihah 2/363, and it is with Abu Ash-Shaikh Al-Asfahani in 'Akhlaqun-Nabiyy, pg. 270.
