Sunan Ibn Majah, Chapter: The Chapters on Wills

"A man came to the Prophet (saw) and said: "O Messenger of Allah (saw), tell me, which of the people has most right to my good companionship?' He said: 'Yes, by your father, you will certainly be told.' He said: 'Your mother,' He said: 'Then who?' He said: Then your mother.' He said: 'Then who?' He said: Then your mother.' He said: 'Then who?' He said: Then your father.' He said: 'Tell me, O Messenger of Allah (saw) about my wealth - how should I give in charity?' He said: 'Yes, by Allah (swt) you will certainly be told. You should give in charity when you are still healthy and greedy for wealth, hoping for a long life and fearing poverty. Do not tarry until your soul reaches here and you say: "My wealth is for so-and-so," and "My wealth is for so-and-so," and it will be for them even though you dislike that.'" Sahih
