The Statement of Allah the Most High: "Then wait you for the Day when the sky will bring forth a visible smoke." (V.44:10)

Sahih al-Bukhari · Book 65 · Hadith 4820

حَدَّثَنَا عَبْدَانُ، عَنْ أَبِي حَمْزَةَ، عَنِ الأَعْمَشِ، عَنْ مُسْلِمٍ، عَنْ مَسْرُوقٍ، عَنْ عَبْدِ اللَّهِ، قَالَ مَضَى خَمْسٌ الدُّخَانُ وَالرُّومُ وَالْقَمَرُ وَالْبَطْشَةُ وَاللِّزَامُ‏.‏

Narrated `Abdullah: Five things have passed, i.e. the smoke, the defeat of the Romans, the splitting of the moon, Al-Batsha (the defeat of the infidels in the battle of Badr) and Al-Lizam (the punishment)'.
