Sayyiduna Ibn Abas narrates that I used to graze a cow belonging to my family. One day, by His command, I heard this voice: "O family of Zareeh, a clear statement!" A person was announcing and saying, "There is no deity except Allah." After that, when we reached Makkah Mukarramah, we found out that the Prophet (ﷺ) had proclaimed prophethood.
