give good news to others

[Umme Fatimah]

Abu Musa Radiyallahu anhu narrates that
Nabi Sallallahu alaihi wasallam said:
Take good news, and give good news to others,
that he, who bears witness to
La ilaha illallahu
(there is none worthy of worship except Allah)
and is truthful in his testimony thereof,
will enter Paradise.

{ Musnad Ahmad, Tabarani, Majma-uz-Zawaid}
