Musnad Ahmad 1180:1

Yahya narrated to us, from Ibn ‘Ajlan, who said: Bukayr ibn ‘Abdullah ibn al-Ashajj narrated to me, from Busr ibn Sa‘id, from Zaynab, the wife of ‘Abdullah, from the Messenger of Allah (may Allah bless him and grant him peace), who said: "And if one of you women attends the 'Isha' (night) prayer, let her not touch any perfume."
