The Prophet’s (saw) message is not limited to one group of people.
The Prophet (saw) did not overload his companions with information;
Allah (swt) said: “Reciting unto them His verses (the Qur’an), and purifying them (from sins by their following him), and instructing them (in) the Book (the Qur’an) and al-Hikmah (the wisdom).” (Qur’an: 164)
