It is narrated from Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him), he says: I came to the Noble Prophet (peace and blessings be upon him), while some people from my tribe were also with me. The Prophet (peace and blessings be upon him) said: "Rejoice yourselves and give glad tidings to those who come after you that whoever sincerely bears witness that Allah alone is the true deity, he will enter Paradise." Hearing this, we left the presence of the Noble Prophet (peace and blessings be upon him) to give people the glad tidings, but when we met Sayyiduna Umar (may Allah be pleased with him) ahead, he sent us back to the Messenger of Allah (peace and blessings be upon him) and advised him that (such things should not be told to the common people, otherwise) they will rely on it (and abandon deeds). Hearing this, the Messenger of Allah (peace and blessings be upon him) remained silent.
