(1) باب الْكَرَاهِيَةِ فِي تَأْخِيرِ الْوَصِيَّةِ
It was narrated from Mutarrif, from his father, that the Prophet said:
"The mutual rivalry (for piling up of worldly things) diverts you, 'Until you visit the graves (i.e. till you die).' The son of Adam says: 'My wealth, my wealth,' but your wealth is what you eat and consume, or what you wear and it wears out, or what you give in charity and send on ahead (for the Hereafter).'"
