Sahih al-Bukhari 129
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).
حَدَّثَنَا مُسَدَّدٌ، قَالَ حَدَّثَنَا مُعْتَمِرٌ، قَالَ سَمِعْتُ أَبِي قَالَ، سَمِعْتُ أَنَسًا، قَالَ ذُكِرَ لِي أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ لِمُعَاذٍ ‏"‏ مَنْ لَقِيَ اللَّهَ لاَ يُشْرِكُ بِهِ شَيْئًا دَخَلَ الْجَنَّةَ ‏"‏‏.‏ قَالَ أَلاَ أُبَشِّرُ النَّاسَ قَالَ ‏"‏ لاَ، إِنِّي أَخَافُ أَنْ يَتَّكِلُوا ‏"‏‏.‏
