Sulaiman al-A'mash الأعمش / سليمان بن مهران · The Book of Wills

"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).'"

"A man made a will leaving some Dinars (to be spent) in the cause of Allah. Abu Ad-Darda' was asked about that, and he narrated that the Prophet said: 'The likeness of the one who frees a slave or gives some charity when he is dying, is that of a man who gives a gift after he has eaten his fill.'"

"The Messenger of Allah said: 'It is not befitting for a Muslim who has anything concerning which a will should be made, to abide for two nights without having a written will with him.'"
