Sahih al-Bukhari 6666

Ahmad ibn Yunus narrated to us; Abu Bakr narrated to us, from Abd al-Aziz ibn Rufay, from Ata, from Ibn Abbas, may Allah be pleased with them both, who said: A man said to the Prophet, peace and blessings be upon him, ‘I performed the circumambulation before stoning.’ He said, ‘There is no blame.’ Another said, ‘I shaved my head before slaughtering.’ He said, ‘There is no blame.’ Another said, ‘I slaughtered before stoning.’ He said, ‘There is no blame.’
