Ishaq bin Mansur al-Kausaj إسحاق بن منصور بن بهرام - الكوسج · The Book on Military Expeditions

That on the day of Conquest of Makkah, the Messenger of Allah (ﷺ) said: "There is no Hijrah after the conquest, there is only Jihad and intention, and when you are called to go forth (for battle), then go." There are narrations on this topic from Abu Sa'eed, 'Abdullah bin 'Amr, and 'Abdullah bin Hubshi. This Hadith is Hasan Sahih. Sufyan Ath-Thawri reported it similarly from Mansur bin Al-Mu'tamir.
