I heard Messenger of Allah ﷺ as saying: Allah, the Exalted and Glorious, said: The son of Adam abuses Dahr (the time), whereas I am Dahr since in My hand are the day and the night.  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ قَالَ اللَّهُ ﷻ يَسُبُّ ابْنُ آدَمَ الدَّهْرَ وَأَنَا الدَّهْرُ بِيَدِيَ اللَّيْلُ وَالنَّهَارُ  

Allah, the Exalted and Glorious, said: The son of Adam displeases Me by abusing Dahr (time), whereas I am Dahr--I alternate the night and the day.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ قَالَ اللَّهُ ﷻ يُؤْذِينِي ابْنُ آدَمَ يَسُبُّ الدَّهْرَ وَأَنَا الدَّهْرُ أُقَلِّبُ اللَّيْلَ وَالنَّهَارَ  

Allah, the Exalted and Glorious, said: The son of Adam causes Me pain as he says: Woe be upon the Time. None of you should say this: Woe be upon the Time, as I am the Time (because) I alternate the day and the night, and when I wish I can finish them up.  

قَالَ رَسُولُ اللَّهِ ﷺ قَالَ اللَّهُ ﷻ يُؤْذِينِي ابْنُ آدَمَ يَقُولُ يَا خَيْبَةَ الدَّهْرِ فَلاَ يَقُولَنَّ أَحَدُكُمْ يَا خَيْبَةَ الدَّهْرِ فَإِنِّي أَنَا الدَّهْرُ أُقَلِّبُ لَيْلَهُ وَنَهَارَهُ فَإِذَا شِئْتُ قَبَضْتُهُمَا  

None of you should say: Woe be upon the Time, for verily Allah is the Time.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَقُولَنَّ أَحَدُكُمْ يَا خَيْبَةَ الدَّهْرِ فَإِنَّ اللَّهَ هُوَ الدَّهْرُ  

Do not curse Time, for it is Allah Who is Time.  

عَنِ النَّبِيِّ ﷺ قَالَ لاَ تَسُبُّوا الدَّهْرَ فَإِنَّ اللَّهَ هُوَ الدَّهْرُ
