I was informed that the Prophet ﷺ had said to Muʿadh, "Whosoever will meet Allah without associating anything in worship with Him will go to Paradise." Muʿadh 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). (Using translation from Bukhārī 129)
أَنَّ النَّبِيَّ ﷺ قَالَ لِمُعَاذِ بْنِ جَبَلٍ «مَنْ لَقِيَ اللهَ لَا يُشْرِكُ بِهِ شَيْئًا فَلَهُ الْجَنَّةُ» قَالَ أَلَا أُبَشِّرُ النَّاسَ؟ قَالَ «لَا يَتَّكِلُونَ»
