Chapter : Not known.
Narated By ‘Aisha, Ummul Mu’minin : We were proceeding to Mecca along with the Prophet (PBUH). We pasted on our foreheads the perfume known as sakk at the time of wearing ihram. When one of us perspired, it (the perfume) came down on her face. The Prophet (PBUH) saw, but did not forbid it.
