The Noble Scholar Shaykh Ibn Baz (may Allah have mercy upon him) said:

The legislation for the Muslim when he hears a benefit is that he is to convey to others. Likewise the Muslimah conveys to others what she has heard from the knowledge due to the statement of the Prophet  صلى الله عليه وسلم:

ﺑﻠﻐﻮﺍ ﻋﻨﻲ ﻭﻟﻮ ﺁﻳﺔ
Convey on me even if it is one matter. (Sahih al-Bukhari 3461)

Also when he would address the people in a sermon he would say:

ﻟﻴﺒﻠﻎ ﺍﻟﺸﺎﻫﺪ ﺍﻟﻐﺎﺋﺐ ﻓﺮﺏ ﻣﺒﻠﻎ ﺃﻭﻋﻰ ﻣﻦ ﺳﺎﻣﻊ
Let the one who witnesses this speech convey to the one who is absent, for it is possible that the one who the information has been conveyed to has more understanding than the one who actually heard it. (Sahih al-Bukhari 1741)
