Abd Allaah bin Amr bin Al ‘As said “The Messenger of Allah ﷺ stopped during the Farewell Pilgrimage at Mina, as the people were to ask him (about the rites of Hajj). A man came and said Messenger of Allah being ignorant, I shaved before sacrificing. The Messenger of Allah ﷺ replied “Sacrifice, for no harm will come. ” Another man came and said “Messenger of Allah ﷺ, being ignorant, I sacrificed before throwing the pebbles. ” He replied “Throw them for no harm will come. ” He (the Prophet) was not asked about anything which had been done before or after its proper time without saying “Do it, for no harm will come. ”

Usamah bin Sharik said “I went out with the Prophet ﷺ to perform Hajj, and the people were coming to him. One would say “Messenger of Allah ﷺ I ran between Al Safa’ and Al Marwah before going round the Kaabah or I did something before the its proper time or did something after its proper time. He would reply “No harm will come; no harm will come except to one who defames a Muslim acting wrongfully. That is the one who will be in trouble and will perish.
