Infants remember six-month-old youngest martyr of Karbala

In this ceremony mothers along with their sucklings, receive the presented cloths in the beginning of their arrival (Alavi's green gown and scarf and the forehead band of Ya Sahebazzaman) will start the mourning of six month immolate of Karbala.

the most reliable narration is quoted by Ibn Jawzi from Hisham b. Kalbi who said when Imam al-Husayn (a) saw that kufan army persisted to kill him, took the Qur'an on his head addressing them, "This book of the Qur'an and the Prophet Muhammad (s) will judge between me and you. Oh, people! How do you assume killing me lawful?"

At this time, Imam (a) saw one of his children was crying of thirst; thus he (a) took him on his hand and said, 'O People! If you show no mercy to me; Have mercy on this thirsty child!" At this moment, someone from Kufan army threw an arrow towards 'Ali al-Asghar (a).

Imam al-Husayn (a) cried hard and said, "O God! Judge between us and the people who invited us to help us but they killed us!" Then, Imam al-Husayn (a) took his hand under Abd Allah's neck and when his hand filled with blood, threw it all up to sky. Then, Imam al-Husayn (a) said, "what makes all these hardships easy for me is the fact that all of this is happened in the presence of God." It is narrated from Imam al-Baqir (a) that none of that blood returned down or poured on earth.

Imam al-Husayn (a) returned the body of 'Ali al-Asghar (a) to the tents for burying.

Some historians have mentioned that after the martyrdom of Ali al-Asghar (a), Imam al-Husayn (a) said, "O God! The martyrdom of this child is not less importance of martyrdom of Naqih Salih (the camel in the tribe of the Prophet Salih(s)) before You! So, if today, You have prevented us from the victory, assign better things for us!"

It is narrated that Imam al-Husayn (a) dug a grave using his sword and buried Ali al-Asghar (a). But, some historians mentioned that Husayn (a) took the bloodstained body back to tents and gave it to his honorable sister Zaynab (s). Also, it is mentioned that Imam (a) put the body next to bodies of other martyrs.
