We read in Al Isaba:
After the battle of Qudsiya Hujr ibn Adi participated in Jamal and Sifeen, alongside Ali and was amongst his Shi’a. He was killed upon the orders of Mu’awiya in a village called Marj Adhra near Damascus. At the time of his execution he requested: ‘Do not remove these chains after I am killed, nor clean the blood. We will meet again with Mu’awiya and I shall petition my case against him’.
We read in Al Bidaya:
When the time of death approached Mu’awiya, he said to himself thrice: ‘Hujr bin Adi! The day of answering for your murder is very lengthy’
We read in Tarikh ibn Asakir:
“Ayesha said: ‘Mu’awiya you killed Hujr and his associates, By Allah! The Prophet told me ‘In the ditch of Adra seven men will be killed, due to this all the skies and Allah will be upset”.
We read in Asad’ul Ghaba:
“Hujr and his associates were arrested and taken to a ditch in Adhra which was near Damascus. Mu’awiya ordered that Hujr and his associates be executed in this ditch”
Hujr bin Adi al-Adbar was a pious lover of Maula Ali (as). Mu’awiya made his bastard brother the Governor of Kufa, he would disgrace the family of the Prophet (s) whilst standing on the pulpit, Hujr as a true lover of Maula ‘Ali (as) was unable to tolerate such insults. He would praise Maula ‘Ali (as) and object to such insults. Ibn Ziyad through his usual deception fabricated allegations to Mu’awiya who ordered that they be apprehended and sent to him. On route to Damascus Mu’awiya ordered their execution. This is a fact that the Nawasib cannot escape, a fact that has even been vouched for by the Salafi scholar scholar Hasan bin Farhan al-Maliki who on page 170 of his book ‘Qeraah fi Kutub al-Aqaed’ said:
“The Bani Umaya killed and humiliated the lovers of Ahl ul bayt, and ruthlessly killed Hujr bin Adi during Mu’awyia’s reign on account of his criticism of their act of cursing Ali from the pulpits”
It is also said that when the time came when they were about to murder Hujr they asked him according to the customs if there was one last request that they could grant him. Hujr asked them if they could kill his son in front of him before they killed him. The executioner asked what was the reason for this? Hujr said that he would like to see that his son would die with the love of Ali in his heart and that he was afraid that if he himself was killed first then his son might leave on account of fear and go over to the side of Muawiya and denounce Ali.
These cruel heartless people then murdered Hujr’s son in front of him and then proceeded to murder Hujr next.
May Allah bless Hujr ibn Adi, his son and his faithful companions!
