If there were two valleys of gold for the son of Adam, he would long for another one. and his mouth will not be filled but with dust, and Allah returns to him who repents.
Sahih Muslim Book 12, Hadith 154
← Previous Hadith I heard the Messenger of Allah (ﷺ) as saying this, but I do not know whether this thing was revealed to him or not, but he said to.

Sahih Muslim Book 12, Hadith 153 Next Hadith → If there were for the son of Adam a valley full of riches, he would long to possess another one like it. and Ibn Adam does not feel satiated but with dust. And Allah returns to him who returns (to Him). Ibn Abbas said: I do not know whether it is from the Qur'an or not; and in the narration transmitted by Zuhair it was said: I do not know whether it is from the Qur'an, and he made no mention of Ibn Abbas.
