Surat Al-Muddaththir (The Cloaked One) - المدثر

وَكُنَّا نَخُوضُ مَعَ ٱلْخَآئِضِينَ ﴿٤٥﴾ وَكُنَّا نُكَذِّبُ بِيَوْمِ ٱلدِّينِ﴿٤٦﴾ حَتَّىٰٓ أَتَىٰنَا ٱلْيَقِينُ﴿٤٧﴾

And we used to enter into vain discourse with those who entered into vain discourses. And we used to call the day of judgment a lie; Till death overtook us.
