If someone performs the funeral prayer, is he permitted to leave without the group's permission?

Imam Zuhri states that Hazrat Miswar bin Makhramah would not return after the funeral prayer until he had taken permission.

Hazrat Zaid bin Thabit says: When you have performed the funeral prayer, then you have fulfilled your duty; now leave him and his family alone (empty).

Hazrat Jabir narrates that accompany the funeral procession as much as you wish, then return when it becomes apparent to you.

Ibn Aun states that Muhammad did not consider seeking permission necessary, and used to say that they are not guardians over us.

Hazrat Musa bin Nafi' says that I saw Hazrat Saeed bin Jubair; he offered the funeral prayer and then returned.

Hazrat Ibn Juraij states that a person asked Hazrat Nafi whether Hazrat Abdullah bin Umar (may Allah be pleased with both of them) used to return before permission after finishing the funeral prayer. He replied that he did not use to return before taking permission.

Ibrahim says that two persons, despite not holding the position of leadership, are still considered as leaders: one is the owner of a funeral—when you have performed the funeral prayer, do not return without his permission; and the menstruating woman among her companions when she becomes menstruating.

Hazrat Abdullah says that two people, despite not being leaders, are still considered leaders: the one at a funeral, and a menstruating woman among her companions.

The same is narrated from Hazrat Umar.

Hazrat Talha al-Yami says: Two people, though not actually leaders, are considered leaders. The funeral is the leader for the one who follows it, and a menstruating woman is the leader among her companions when she becomes menstruating.

Hazrat Dawood bin Abi Al-Qassaf says that I was with Hazrat Abu Qalabah at a funeral. When he performed the prayer, he returned. I said to him, "Are you leaving before permission?" He replied, "Are they rulers (and imposed) over us?"

Hazrat Abu Dawood Al-Tayalisi says that I asked Hazrat Abu Aqil, "Is it permissible for a person who is with a funeral procession to return (before completion)?" He replied, "No, but it is part of a man's modesty that he should not return without permission."

Hazrat Abu Huraira (may Allah be pleased with him) narrates: There are two leaders who are not truly leaders. One is a woman who goes with a group for Hajj or Umrah and she becomes menstruating; now the group cannot depart until she becomes pure or gives them permission to leave while she is still impure. And the second is a man who goes with a funeral procession; now he cannot return until he is given permission or until the deceased is buried.

Hazrat Habib bin Abi Muhammad says that I was with Hasan at a funeral, then when people were given permission, I said to Hasan, "Permission has been given." Hasan said, "Is permission (necessary) for us?"

Hazrat Jabir says: Accompany the funeral procession as much as is apparent (possible) for you, and return when it becomes apparent (possible) for you.

It is narrated from Hasan in a similar manner.

Hazrat Abu Huraira (may Allah be pleased with him) narrates that there are two people who, despite not being wealthy, are considered wealthy: If a person performs the funeral prayer, he should not return without permission; and if a woman (during the journey of Hajj) gets her menses on the Day of Sacrifice before performing Tawaf, then it is not permissible for them to leave without that woman's permission.
