Rule Of Action
Suppose a Mufrid or a Qarin or a Mutamatte got his head shaven before Rami or suppose a Qarin, or a Mutamatte got his head shaven before offering sacrifice, or suppose a Qarin or a Mutamatte offered sacrifice before Rami ; in all such cases a Dam would be obligatory, because a proper arrangement was obligatory to perform these practices. For a Mufrid however, this arrangement of performance is obligatory only in Rami and Halq (having his head shaven) as he is not obliged to offer a sacrifice. On the other hand, for a Qarin this arrangement is obligatory to perform Rami, sacrifice and Halq. He should first perform Rami, then offer sacrifice and then should have his head shaven. In case of priority or delay a Dam would be obligatory.
Rule Of Action
After offering sacrifice it is Wajib to have your head shaven or your hair cut equal in length to a joint of a finger (about one inch). But it is not necessary to be done today. It may be done at any time upto the 12th of Zilhijja but you will remain under the restrictions of Ihram whatever length of time you may pass until you have your head shaven or your hair cut. In case you have your head shaven or your hair cut on the 10th of Zilhijja you will be relieved from Ihram formalities. Now, wearing sewn clothes, using perfumes, pruning nails and having your hair cut, all these things become lawful for you, but your enjoying a sexual intercourse with your wife will not be lawful until you are relieved from the obligation of Tawaf-e-Ziyarat i.e. Tawaf-e-
It is Wajib for a Qarin and a Mutamatte’ that after being free from Rami they do not have their heads shaven or their hair cut until they discharge their Wajib of offering sacrifice ; otherwise they will fall under the obligation of Dam. Offering sacrifice is not Wajib, of course, for a Mufrid who has worn Ihram for Hajj only. For him, it is Mustahab only. It is lawful for him not to offer any sacrifice and to have his head shaven.
