Based on all that...

Based on all that, it is most likely that he (Q) had left to Karbala by a miracle on the thirteenth day to bury the bodies.

Going back to Karbala, where the demises of Ahlu El-Bayt (R), we find that the women of Bani Asad (the people of Asad) went to where the dead bodies were while crying and weeping and they said to their husbands: "How are you going to apologize for the Messenger of Allah (P), the Prince of the believers (Q), and Lady Fatima El-Zahra (O) when you face them while you did not support his sons, you did not defend them with neither a sword strike, a spear stab, nor with a single arrow?!" The men said to them: "Indeed, we are afraid of the Umayyad people!" So the women kept going around them while saying to them: "Since you had missed supporting this prophetic group, you should hasten now to bury their pure bodies…".

They said: "We will do that..". Their main concern was to bury the body of Imam Hussain (Q) first and then the rest of the bodies. They started looking at the cops in the battle field, but were not able to tell which one was of Imam Hussain (Q) since their heads were cut off and the sun had changed their skin color.

While they were in that state, a knight came to them and when he reached them he said: "What is the matter?" They said: "We came to bury the body of Imam Hussain (Q) and the bodies of his children and supports, but we don’t know which body is for Imam Hussain (Q)” Then he said to them: "I will guide you".

He went down from his horse back and started walking between the dead bodies till he saw the body of Imam Hussain (Q), so he hugged it while crying and saying: "O Father, killing you had pleased the eyes of the gloaters! O Father, the Umayyad people are happy with your murder, O Father, after your martyrdom our grief is extended!
