Ritual 162

It is not permissible to delay wearing ihram from Dhul Hulaifah and wearing it at Johfa instead, except for a valid reason, such as sickness or due to weakness.

2. Wadil-Aqeeq which is the Meqat for the people of Iraq and Najd and those passing through there. It has three parts: Maslakh, Ghamrah and Thati Irq. The preferred view (al ahwatil awla), is for a pilgrim to wear his ihram before reaching Thati Irq, if there is no case for dissimulation (taqiyyah) or illness.
