‘Abdallah b. Mas'ud reported God’s Messenger as saying, “No man who acquires unlawful property and gives some of it in alms will have it accepted from him; neither will he receive a blessing for it if he con-tributes some of it; and if he leaves some of it behind him (i.e. when he dies) it will be his provision for hell. God does not obliterate an evil deed by an evil one, but He obliterates an evil deed by a good one. What is impure does not obliterate what is impure.”
Ahmad transmitted it, and the same is given in Sharh as-sunna.
Narrated ‘A'isha reported the Prophet as saying, “The pleasantest things you enjoy come from what you earn, and your children come from what you earn”*. The version of Aba Dawud and Darimi has, “The pleasantest things a man enjoys come from what he earns and his child comes from what he earns.”
Tirmidhi, Na:
the children are the result of marriage, and parents who are in need may receive support from their children.
Jabir reported God’s Messenger as saying, “Flesh which has grown out of what is unlawful will not enter paradise*, but hell is more fitting for all flesh which has grown out of what is unlawful.”
Ahmad, Darimi, and Baihaqi, in Shu'ab al-iman, transmitted it.
*The reference here is to people who live on unlawful source of income.
Anas said that Abu Taiba cupped God’s Messenger and he ordered that sa’ of dates be given him, also ordering his people to remit some of his dues.*
* Abu Taiba was a client of the B. Haritha. It was the custom for a slave to hand over to his master part of what he earned. Here the Prophet suggests that the masters of Abu Taiba should reduce the amount they took from him.
