The ruling on delaying the Sa'y after the Tawaf
Question :
What is the ruling on the person who performs Tawaful- Ifadhah and he does not perform Sa'y until the sun sets after the last days of At-Tashreeq? And what is the ruling on the Sa'y if the person performed Sa'y after sunset on that day and after the days of At-Tashreeq?
Answer:
Your performing Sa'y during the last days of At-Tashreeq or after the days of At-Tashreeq is correct. There is no sin on you in delaying it, because it is not a condition of its correctness that it must be done with the Tawaf. However, it is from perfection that it is done along with the Tawaf - immediately after it in following the Prophet ﷺ.
