The prophet Malachi described this as a spiritual cleansing. History shows that this took place between 1914 and the early part of 1919.
بَعْدَمَا طَهَّرَ ٱلْمَلِكُ ٱلْمُتَوَّجُ ٱلسَّمَاءَ مِنَ ٱلتَّأْثِيرِ ٱلْمُفْسِدِ لِلشَّيْطَانِ وَأَبَالِسَتِهِ ،‏ وَجَّهَ يَهْوَهُ ٱبْنَهُ يَسُوعَ لِيَتَفَقَّدَ وَيُمَحِّصَ أَتْبَاعَهُ عَلَى ٱلْأَرْضِ .‏
