From Sahih Bukhari (Hadith 1754):
Narrated `Abdur-Rahman bin Al-Qasim:I heard my father who was the best man of his age, saying, "I heard `Aisha saying, 'I perfumed Allah's Apostle with my own hands before finishing his Ihram while yet he had not performed Tawaf-al- Ifada.' She spread her hands (while saying so)
