It is narrated from Tawus (may Allah have mercy on him) that he said: The Messenger of Allah (peace and blessings be upon him) did not appoint Dhat 'Irq as a miqat, nor were there people from the east at that time. Rather, it is the people who have appointed Dhat 'Irq as a miqat. Imam Shafi'i (may Allah have mercy on him) said: In my opinion as well, the matter is as Tawus (may Allah have mercy on him) has stated, and better knowledge is with Allah.
