The Companions’ struggle over the Prophet’s (peace and blessings be upon him) ablution water at the Treaty of al-Hudaybiyyah: Does it not indicate that used water removes ritual impurity?

Question:
May Allah reward you, Your Eminence, father. The questioner says: We previously established in the chapter on water that water used to remove a state of ritual impurity is pure but does not remove the state of ritual impurity. He asks: How do we respond to those who cite the hadith of the Companions (may Allah be pleased with them) struggling over the ablution water of the Prophet (peace and blessings be upon him) at the Treaty of al-Hudaybiyyah as evidence?

Answer:
This was not for them to perform ablution with, but rather to seek blessing in the traces of the Messenger (peace and blessings be upon him) that separated from his body, such as the water from his ablution, his sweat, his saliva, and his clothes. These things separated from the Messenger (peace and blessings be upon him), so they sought blessing in them, not intending to perform ablution with them. There is a difference between these two things. Did they say that they would perform ablution with it after the Messenger (peace and blessings be upon him)? No, they only competed for it in order to seek blessing.
