I came to the Prophet ﷺ with a group of my people, and he said, "Rejoice, and bring glad tidings to those you left behind. Whoever testifies that there is no god but Allah, truthful in that testimony, will enter Paradise."So we left the Prophet ﷺ to bring the good news to people, but Umar bin Khattab met us and brought us back to the Messenger of Allah.Umar said, "Messenger of Allah, in that case, people will simply rely on it."The Messenger of Allah ﷺ remained silent.
أتيت النبي ﷺ ومعي نفر من قومي، فقال: أبشروا وبشروا من وراءكم، إنه من شهد أن لا إله إلا الله صادقا بها دخل الجنة، فخرجنا من عند النبي ﷺ نبشر الناس، فاستقبلنا عمر بن الخطاب، فرجع بنا إلى رسول الله، فقال عمر: يا رسول الله إذن يأكل الناس، قال: فسكت رسول الله ﷺ.
Ahmad (19597, 19689) narrated it through two paths from Hammad bin Salama, who said, "Abu Imran Jawni narrated to us, from Abu Bakr bin Abu Musa, from his father Abu Musa Ashari," and he related it. Its isnad is sahih. Abu Bakr's name was Amr or Amir, and he is trustworthy. Abu Dawud said, "I think he heard from his father."
