Musnad Ahmad Hadith 17669

It is narrated from Amr bin Kharijah (may Allah be pleased with him) that (in the plain of Mina) the Prophet (ﷺ) delivered a sermon while sitting on his she-camel (which was chewing cud and its saliva was flowing between my two shoulders) and said: Remember, charity is not lawful for me and my family. Then he took a hair from the shoulder of his she-camel and said: Not even equal to this. Upon such a person is the curse of Allah, the angels, and all people 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 deeds will be accepted. The child belongs to the (owner of the) bed, and for the adulterer is the stone. Allah Almighty has given every rightful person his right, therefore, there can be no bequest in favor of an heir.
