Fasting
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 Yahya:Hisham said, "My father said that 'Aishah (ra) used to observe Saum (fast) on the days of Mina." His (i.e., Hisham's) father also used to observe Saum on those days
