I heard the Prophet (ﷺ) saying, "The reward of deeds depends on the intentions, so whoever emigrated for the worldly benefits or to marry a woman, his emigration was for that for which he emigrated, but whoever emigrated for the Sake of Allah and His Apostle, his emigration is for Allah and His Apostle."
Sahih al-Bukhari Book 63, Hadith 123
← Previous Hadith We visited Khabbaba who said, "We migrated with the Prophet (ﷺ) for Allah's Sake, so our reward became due and sure with Allah. Some of us passed away without taking anything of their rewards (in this world) and one of them was Mus`ab bin `Umar who was martyred on the day (of the battle) of Uhud leaving a striped woolen cloak. When we covered his head with it, his feet became naked, and when covered his feet, his head became naked. So Allah's Messenger (ﷺ) ordered us to cover his head and put some Idhkhir (i.e. a special kind of grass) on his feet. (On the other hand) some of us have had their fruits ripened (in this world) and they are collecting them."

Sahih al-Bukhari Book 63, Hadith 122 Next Hadith → `Abdullah bin `Umar used to say, "There is no more Hijrah (i.e. migration) after the Conquest of Mecca."
