It is reported that when Imam Hussein (Peace be upon him) was killed not only the residents of the heavens wept for him, but also the skies cried and wept blood for his martyrdom. This is reported not only in Shi’a books but also in most important Bakri (Sunni) references:
“
On the day of al-Hussein’s (Peace be upon him) martyrdom, the sky rained blood”. See: Thakhaa’er al-Uqba pp144, 145, 150. Al-Sawaa’eq al-Muhriqah pp116, 192.
“
There was not a stone which was not lifted but underneath it blood was found”. See: Al-Sawaa’eq al-Muhriqah pp116, 192. Tathkirat-ul-Khawaas p 284, Tafsir ibnKathir vol. 9,p162.
There are many more traditions and references in this respect, and it should be noted that the skies everywhere wept blood for Imam Hussein(Peace be upon him).
Here is another report quoted, which was based in Britain that indicates the skies wept blood for Imam Hussein (Peace be upon him) everywhere:
“
685. In this year in Britain it rained blood, and milk and butter were turned into blood”. see: The Anglo-Saxon Chronicle, Translated, edited by G.N. Garmonsway, Professor of English, King’s College,London.
The year 685ad is the same year which Imam Hussein (Peace be upon him) was martyred in.
