‘Abdullāh ibn Mas‘ūd (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "Do not crave for property lest you should become consumed with desire for worldly life."
شرح الحديث :
The Prophet (may Allah's peace and blessings be upon him) warned against preoccupation with this life, and against craving for wealth through trade, industry, and real estate, since this distracts one totally from the affairs of the Hereafter, which humans were originally created for.
