Hadith.2538 - Muhammad al-Halabi asked Abu Abdullah (as) about the use of khayri (a type of oil derived from flowers) and banafsaj (violet oil) for anointing oneself when intending to enter Ihram.
Imam (as) replied: "Yes, it is permissible."
Muhammad then asked him about a person who performs ghusl (ritual bath) in Medina for their Ihram.
Imam (as) said: "It suffices them, and they do not need to perform another ghusl at Dhul-Hulayfah."
