The procession of the servants of the two holy shrines to commemorate the martyrdom anniversary of Imam Zayn Al-'Abideen (peace be upon him) was launched on the afternoon of the 25th of Muharram 1437 AH corresponding to the 8th November 2015.
The procession of the servants of the Al-Abbas's (p) holy shrine, which revives the rituals of this occasion was launched, went out of the holy shrine of the Moon of Bani Hashem Abu Al-Fadl Al-Abbas (peace be upon him) heading towards the shrine of Imam Al-Hussayn (peace be upon him) to present their condolences to him and to their servants and to the Islamic world, then condolences rituals were held at the holy shrine of Imam Al-Hussayn (peace be upon him) to commemorate this sad occasion.
Imam As-Sajjad (peace be upon him) enjoyed great popularity. The people spoke with admiration about his knowledge, his jurisprudence, and his acts of worship. The assemblies admired his patience and all his other qualities. The Imam occupied the hearts and feelings of the people. Hence blessed was he who saw him, met him, and listened to his words.
This situation frightened the Umayyads, especially as it concerns al-Walid b. 'Abd al-Malik, who was the most spiteful toward the Imam. It is reported on the authority of al-Walid b. 'Abd al-Malik, who said: "I cannot have a rest as long as Ali Ibn Al-Hussayn is in this world!
When al-Walid became king, he decided to assassinate the Imam. He sent poison to his governor of Medina, and ordered him to mix the poison (with liquid) and give it to the Imam to drink. The poison reacted on the Imam's body, and he suffered severe pain. The Imam remained on the bed of illness for some days. He (peace be upon him) praised and lauded Allah for providing him with martyrdom at the hand of the most wicked creature.
Then the Imam's great soul went to its Creator, as the souls of the prophets and the messengers did. Allah's angels, favors and greetings surrounded it with magnification and admiration. This great soul met its Creator after it had illuminated the horizons of this world with knowledge, worship, and freedom from all inclinations of caprice.
Imam Abu Ja'far Al-Baqer (peace be upon him) undertook the preparation of the corpse of his father. He washed his pure body, shrouded it, and prayed over it. Great escorting was held for the Ima`m. Medina (Yathrib) had never witness such escorting before. In the middle of a halo of exclaiming Allah is great and praising Him, the people brought the Holy Corpse to al-Baqi Cemetery. They dug a grave for him beside the grave of his pure uncle, Imam Al-Hassan, the master of the youths of Paradise, and the plant of sweet basil of Allah's Apostle, may Allah bless him and his family. Then Imam Al-Baqer, peace be upon him, buried his father in his final resting place.
