Hadith on Greed: If he had all the gold, he still wants more

Anas bin Malik reported: The Messenger of Allah, peace and blessings be upon him, said, “If the son of Adam had a valley full of gold, he would want to have two valleys. Nothing fills his mouth but the dust of the grave, yet Allah will relent to whoever repents to him.”

عن أنس بن مالك أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ لَوْ أَنَّ لاِبْنِ آدَمَ وَادِيًا مِنْ ذَهَبٍ أَحَبَّ أَنْ يَكُونَ لَهُ وَادِيَانِ وَلَنْ يَمْلأَ فَاهُ إِلاَّ التُّرَابُ وَيَتُوبُ اللَّهُ عَلَى مَنْ تَابَ
