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

عن عبد الله بن عباس رضي الله عنهما قال: قال رسول الله صلى الله عليه وسلم يوم فتح مكة: «لا هجرة بعد الفتح، ولكن جهاد ونية. وإذا اسْتُنْفِرْتُم فَانْفِرُوا. وقال يوم فتح مكة: «إن هذا البَلد حَرَّمَهُ الله يوم خلق الله السموات والأرض، فهو حَرَامٌ بحُرْمَةِ الله إلَى يوم القيامة، وإنه لم يحل القتال فيه لِأَحَدٍ قَبْلِي، ولم يَحِلَّ لي إلا ساعة من نهار، حرام بِحرمة الله إلى يوم القيامة، لا يُعْضَدُ شَوْكُهُ، وَلاَ يُنَفَّرُ صَيْدُهُ، وَلاَ يَلْتَقِطُ لُقَطَتَهُ إلا من عَرَّفَهَا، ولاَ يُخْتَلَى خَلاَهُ». فقال العباس: يا رسول الله، إلا الإِذْخِرَ؛ فإنه لِقَيْنِهِمْ وبيوتهم؟ فقال: «إلا الإِذْخِرَ».

‘Abdullāh ibn ‘Abbās (may Allah be pleased with him) reported: On the day of the Conquest of Makkah, the Messenger of Allah (may Allah's peace and blessings be upon him) said: "There is no emigration after the Conquest (of Makkah), but there is Jihad and good intention, and whenever you are called for Jihad, you should immediately respond to the call." On the same day, he added: "Verily, Allah has made this city sacred since the day He created the heavens and the earth. Thus, it is a sanctuary by Allah’s decree until the Day of Judgment. Fighting in it was not permissible for anyone before me, and it was made permissible for me for only an hour of a day. It is sacred by the sacredness granted by Allah until the Day of Judgment. Its thorns should not be cut off, and its game should not be chased, and any lost item found therein should not be picked up except by one who would announce it publicly, and its green grass should not be cut off." Al-‘Abbās said: "O Messenger of Allah, except for lemongrass, for it is used by their blacksmiths and for their domestic purposes.' So, the Prophet (may Allah's peace and blessings be upon him) responded: "Except for lemongrass."
