It was narrated from Anas bin Malik that the Messenger of Allah ﷺ said:
"Hasten to do good deeds (before) six things (happen): The rising of the sun from the west (place of its setting), the smoke, the beast of the earth, Dajjal (False Christ), that which will happen to each of you (death); and that which will happen to all people (the Day of Resurrection)."

حَدَّثَنَا حَرْمَلَةُ بْنُ يَحْيَى، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ وَهْبٍ، أَخْبَرَنِي عَمْرُو بْنُ الْحَارِثِ، وَابْنُ، لَهِيعَةَ عَنْ يَزِيدَ بْنِ أَبِي حَبِيبٍ، عَنْ سِنَانِ بْنِ سَعْدٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، عَنْ رَسُولِ اللَّهِ ﷺ قَالَ " بَادِرُوا بِالأَعْمَالِ سِتًّا طُلُوعَ الشَّمْسِ مِنْ مَغْرِبِهَا وَالدُّخَانَ وَدَابَّةَ الأَرْضِ وَالدَّجَّالَ وَخُوَيْصَّةَ أَحَدِكُمْ وَأَمْرَ الْعَامَّةِ " .
