From Sahih Muslim (Hadith 3200):
Al-Qasim reported the Mother of the Faithful (Hadrat 'A'isha Siddiqa) (Allah be pleased with her) as saying:I used to weave these garlands from the multicoloured wool which was with us. The Messenger of Allah (ﷺ) was in the state of non Muhrim among us, and he would do all that was lawful for a lion-Muhrim with his wife
