Narrated Anas:
I was informed that the Prophet (ﷺ) had said to Mu`adh, "Whosoever will meet Allah without associating anything in worship with Him will go to Paradise." Mu`adh asked the Prophet, "Should I not inform the people of this good news?" The Prophet (ﷺ) replied, "No, I am afraid, lest they should depend upon it (absolutely).
