All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
First of all, it should be mentioned that if you had intended to perform ‘Umrah when you first went from Sweden to Jeddah, then you were obligated to assume the state of Ihraam from the Meeqaat by which the plane passed and it was not permissible for you to delay assuming the state of Ihraam until you arrived at Jeddah. Hence, you are obligated to offer a sacrifice which should be slaughtered (in Makkah) and distributed among the poor in Makkah as you neglected one of the obligations of ‘Umrah which is assuming the state of Ihraam from the Meeqaat.
However, if you had not intended to perform ‘Umrah when you went to Jeddah, and when you were in Jeddah you had the intention to perform ‘Umrah, then you were right to assume the state of Ihraam from Jeddah, and in this case, you are not required to do anything.
As regards shortening a small portion of your hair in the two consecutive ‘Umrahs, then if you had shortened or shaved three hairs – as it appears from the question that you did so – then you became out of the state of Ihraam according to many jurists . The Fiqh Encyclopedia reads: “…The obligatory amount (of the hair shaved or shortened to terminate the state of Ihraam) is shaving or shortening the hair of the entire head according to the Maaliki and Hanbali Schools, and at least a quarter of the hair of the head according to the Hanafi School, and at least three hairs according to the Shaafi’i School.”
However, in the future, you should shave or shorten hair from all parts of your head as a way of avoiding the difference of opinion among the scholars and following the Sunnah. For more benefit, please refer to Fataawa 115567 and 84306.
