"A man came to the Prophet and said: 'O Messenger of Allah, what kind of charity brings the greatest reward?' He said: 'To give in charity when you are healthy and feeling miserly, and fearing poverty and hoping for a long life. Do not wait until the (death rattle) reaches the throat and then say: "This is for so and so," and it nearly became the property of so and so (the heirs).'"

Sunan an-Nasa'i Book 29, Hadith 17 Next Hadith → "The Messenger of Allah said: 'For whom among you is the wealth of his heirs dearer to him than his own wealth?' They said: 'O Messenger of Allah, there is no one among us for whom his own wealth is not dearer to him than the wealth of his heirs.' The Messenger of Allah said: 'Know that there is no one among you for whom the wealth of his heirs is not dearer than his own wealth. Your wealth is that which you have sent on ahead, and the wealth of your heirs is that which you have kept.'"
