There is no emigration after the Conquest, but there is Jihad and good intention, and whenever you are called for Jihad, you should immediately respond to the call

Ibn ‘Abbās (may Allah be pleased with him) informs that the Prophet (may Allah's peace and blessings be upon him) delivered a sermon on the Day of the Conquest of Makkah. He said that there is no emigration from Makkah, because it has become part of the Muslim lands. He then ordered the Muslims to fight if they are ordered to, in obedience to Allah, His Messenger and the ruler of the land.

He then spoke of the sanctity of Makkah, and that it has been made sacred since Allah created the heavens and the earth. He said that it was not made lawful for anyone to fight in before him and that it will not be made permissible for any one after him either, as it was made lawful for him to fight therein for only an hour of the day, and then it returned to its original state of sanctity.

He then mentioned that it is not permissible to cut off its thorns or to chase its game, and that no one should pick up lost items found in it except if he wants to announce it. He added that its vegetation should not be cut off, including grass and fodder. He excluded lemongrass because of the benefits it provides to the people of Makkah as it was used by the blacksmiths in starting fire for their work.
