Ibn Mas'ud (May Allah be pleased with him) reported:
Messenger of Allah ﷺ asked, "Who of you loves the wealth of his heir more than his own wealth?" The Companions said: "O Messenger of Allah! There is none of us but loves his own wealth more." He ﷺ said, "His wealth is that which he has sent forward, but that which he retains belongs to his heir."

[Al-Bukhari].

وعنه قال: قال رسول الله ﷺ : “أيكم مال وارثه أحب إليه من ماله؟” قالوا: يا رسول الله، ما منا أحد إلا ماله أحب إليه. قال: "فإن ماله ما قدم ومال وارثه ما أخر" ((رواه البخاري)).
