What type of glistening did 'A'isha (Allah be pleased with her) perceive on the head of Prophet Muhammad (saw) when he was in the state of Ihram?
 'A'isha (Allah be pleased with her) reported:                      I still seem to perceive the glistening of perfume where the hair was parted on Allah's Messenger's (may peace be upon him) head as he was in the state of Ihram.
