Hadith 8:2735
Abu Bakr narrated to us, he said: Waki’ narrated to us, from Muhammad ibn Muslim, from the one who heard ‘Ata’ say: He disliked that one should stone the Jamarat without wudu’, but if he did so, it is sufficient for him.
حدثنا أبو بكر قال نا وكيع عن محمد بن مسلم عمن سمع عطاء يكره أن يرمي الجمار على غير وضوء فإن فعل أجزأه
