Narrated Ibn 'Umar:
Fasting for those who perform ,Hajj-at-Tamattu' (in lieu of the Hadi which they cannot afford) may be performed up to the day of 'Arafat. And if one does not get a Hadi and has not fasted (before the 'Id) then one should fast of the days of Mina. (11, 12 and 13th of Dhul Hajja).
