Musnad Ahmad Hadith 17670

It is narrated from Amr bin Khariyah (may Allah be pleased with him) that (in the plain of Mina) the Prophet (peace and blessings of Allah be upon him) delivered a sermon while sitting on his she-camel (which was chewing cud and its saliva was flowing between my two shoulders) and said: "Be aware, charity is not lawful for me and my family. Then, taking a hair from the shoulder of his she-camel, he said: Not even equal to this. The curse of Allah, the angels, and all people is upon the one who attributes himself to anyone other than his father, or who leaves his master and takes someone else as his ally. None of his obligatory or voluntary acts will be accepted. The child belongs to the (owner of) the bed, and for the adulterer, there are stones. Allah Almighty has given every rightful person his right, therefore, no bequest can be made in favor of an heir." The previous hadith is also narrated through this second chain, but with the addition that none of his obligatory or voluntary acts of worship will be accepted.
