(5) باب صفة الحج ودخول مكة
'Abdullah Ibn 'Amro bin al-'As (RAA) narrated that the Messenger of Allah (ﷺ) stood in Mina during the Farewell Hajj, while the people asked him questions and he answered them. A man asked, 'O Prophet of Allah! I was not alert and I shaved my head before slaughtering my animal?' The Prophet (ﷺ) said:
"There is no harm, go and slaughter your animal." Another man asked, 'l slaughtered the animal before I threw the pebbles? Prophet (ﷺ) said: "There is no harm, go and throw your pebbles." The narrator said: "Whoever asked the Prophet (ﷺ) about anything done before or after the other he told him "No harm done. Go and do (whatever you missed)." Agreed upon.
