(1)    After the completion of the Sacrifice, facing Qibla gents        may do Halaqa or shave their entire head, or get the hair   cut at least one fourth of the hair or make short to the size    of one finger joint.

(2)    Women can only get their hair cut (Qasr), from one fourth of         the entire hair cut at least to the size of one finger joint.      Husband can cut if he is present or she could cut for herself     with a pair of scissors.

(3)    Few person cut a very small portion of their hair with     scissors, without doing Qasr like this the conditions of      ihram do not get over.  It is obligatory (wajib) to cut least   one fourth of the entire hair to the size of at least one finger       joint.

(4)    The hair happen to be uneven in the size, hence, cut the      hair more than that of one finger joint, so that all hair cut to   the required size.

(5)    When the time comes to get out of ihram, then the Muhrim    (or the one who is wearing ihram) can shave his own head      or shave another person’s head, if that person too is a    Muhrim.

(6)    Prior to Halaqa or Taqseer (shaving head or short hair cut)   neither cut your nail nor shape your beard.  Otherwise,   Kaffarah (atonement) would become imperative.

(7)    The time for Halaqa or Taqseer (shaving head or short hair cut) is the days of sacrifice, that is to say, 10^th, 11^th and        12^th of Dhu Al-Hijja and the better day is being the 10^th of Dhu Al-Hijja.

(8)    If Halaqa or Qasr (shaving of the entire head or cutting the   hair short) is not done till 12^th of Dhu Al-Hijja, then giving a        Dam (penalty) is imminent.

(9)    If someone does not have hair on his head or if he is bald,   it is obligatory (wajib) for him to spin the razor on his    head.

(10)  If somebody has measles boils or injuries on his head due   to which he is unable to shave his head or if the hair is not      so long to cut, then Halaqa and Qasr both become waived,       thus everything becomes halaal  for him, as for those who      do Halaqa or Qasr.  But he has to remain in ihram till the         end of the days of Nahar.

(11)  Halaqa or Qasr, doing within the boundaries of Haram is       obligatory (wajib).  If that has been done outside the      boundary, a Dam (penalty) becomes obligatory (wajib).    (Mina is within the boundary of the Haram).

(12)  It is Sunnah to get Halaqa or Qasr done within the Mina

(13)  While getting the Halaqa or Qasr done, sitting facing the       Qibla direction and starting the Halaqa or Qasr from the         right side is Sunna.

(14)  During the Halaqa or Taqseer, recite the takbeer like this :

        “Allahu akbar Allahu akbar.  Laa ilaha illallaahu Allahu akbar.  Allahu akbar wa lillaahil-hamd”

        اَللّٰہُ اَکْبَرُ ط اَللّٰہُ اَکْبَرُ ط لَااِلٰہَ اِلَّا اللّٰہُ وَاللّٰہُ اَکْبَرُ ط اَللّٰہُ اَکْبَرُط وَلِلّٰہِ الْحَمْدُ ط

                “Allah is the Greatest, Allah is the Greatest, none but Allah   is worthy of worship, Allah is the Greatest.  Allah is the     Greatest and all praise belongs to Allah.”

(15)  Prior to and after completion of Halaqa or Taqseer, ask         forgiveness from Allah for self and for the entire Ummah.

(16)  If the Mufarrid wants to give sacrifice, it is recommended      (Mustahab) for him to do Halaqa or Taqseer after the       sacrifice.  If sacrifice is   given after Halaqa then also no        issues. And for the person who performed Tamatto and    Qirran Hajj, it is obligatory (wajib) for them doing Halaqa       or Taqseer after sacrifice is being given. If Halaqa or        Taqseer is done prior to sacrifice being given by them, then    a Dam (penalty) would become obligatory (wajib).

(17)  After getting free from Halaqa or Taqseer (Shaving the         Head or shortening the hair) the restriction of ihram comes         to an end.  But the proximity with the wife and her        anatomical details would be permissible only after the   Tawaf-u-Ziarah        (Circumambulation of the visit)        (Bahar-e-Shariyat,       Volume 1, Part 6, Pages 1142, 1144)
