وَقَالَ لِي مُحَمَّدُ بْنُ الْمُثَنَّى حَدَّثَنَا يَحْيَى، عَنْ هِشَامٍ، قَالَ أَخْبَرَنِي أَبِي كَانَتْ، عَائِشَةُ ـ رضى الله عنها ـ تَصُومُ أَيَّامَ مِنًى، وَكَانَ أَبُوهَا يَصُومُهَا‏.‏

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).
