Hadith 8:3136
Abu Bakr narrated to us, he said: Hushaym narrated to us, from ‘Amr ibn Dinar, from Jabir ibn Zayd, from Ibn ‘Abbas, that the Messenger of Allah (may Allah bless him and grant him peace) delivered a sermon and said: "If the Muhrim (pilgrim in the state of Ihram) does not find an Izar (waist wrapper), let him wear trousers. And if he does not find two sandals, let him wear the Khuffayn (leather socks)."
حدثنا أبو بكر قال نا هشيم عن عمرو بن دينار عن جابر بن زيد عن بن عباس أن رسول الله صلى الله عليه وسلم خطب فقال إذا لم يجد المحرم إزارا لبس سراويل وإذا لم يجد نعلين فليلبس الخفين
