Sahih Muslim 148a
It is narrated on the authority of Anas that verily the Messenger of Allah ﷺ observed: The Hour (Resurrection) would not come so long as Allah is supplicated in the world.
حَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا عَفَّانُ، حَدَّثَنَا حَمَّادٌ، أَخْبَرَنَا ثَابِتٌ، عَنْ أَنَسٍ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ
" لاَ تَقُومُ السَّاعَةُ حَتَّى لاَ يُقَالَ فِي الأَرْضِ اللَّهُ اللَّهُ " .
