Mishkat al-Masabih 10 The Rites of Pilgrimage كتاب المناسك 25

وَعَنْ عَائِشَةَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَقَّتَ لِأَهْلِ الْعِرَاقِ ذَاتَ عِرْقٍ. رَوَاهُ أَبُو دَاوُد وَالنَّسَائِيّ

‘A’isha said that God’s messenger appointed Dhat ‘Irq as the place where the people of al-‘Iraq should put on the ihram. Abu Dawud and Nasa’i transmitted it.
