Narrated by Ibn Umar (R), the Prophet (peace be upon him) said that it is not permissible for anyone to be spared except for two people. One, the person whom Allah Ta'ala has given the tale of recitation of the Qur'an and that day and night there are signs. Second, the person whom Allah has given abundant wealth, and he keeps spending it (day and night) from it. (Bukhari, Tirmidhi, Nasa'i)
