He delayed saa’i until after the days of al-tashreeq
Question

                What is the ruling on one who did tawaaf al-ifaadah but he did not do saa’i until the sun set after the last of the days of al-tashreeq? What is the ruling on saa’i if he did saa’i after sunset on that day or after the days of al-tashreeq?.
Praise be to Allah.
    Your saa’i at the end of the days of al-tashreeq or after the 
    days of al-tashreeq is valid, and there is no sin on you for delaying it, 
    because its validity is not conditional upon it being immediately after 
    tawaaf, although it is better if it is done immediately after tawaaf, 
    following the example of the Prophet  (peace and blessings of Allaah be 
    upon him). 

    And Allaah is the Source of strength. May Allaah send 
    blessings and peace upon our Prophet Muhammad and his family and companions.
