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.
Shaykh Ibn ‘Uthaymeen said: "This is one of the problems that result from giving Fatwa (rulings) without knowledge. In your case, you should return to Makkah and perform Tawaaf Al-Ifaadhah only. You do not have to perform the Farewell Tawaaf as long as you were menstruating when you left Makkah. Ibn ‘Abbaas said, “The Prophet, sallallaahu ‘alayhi wa sallam, ordered people to perform the farewell Tawaaf as the last thing before leaving Makkah, but he excused women who were menstruating.” Also, when the Prophet, sallallaahu ‘alayhi wa sallam, was told that Safiyyah had performed Tawaaf Al-Ifaadhah, he said that she could leave Makkah. This proves that women who are menstruating do not have to perform the Farewell Tawaaf, but they must perform Tawaaf Al-Ifaadhah. As long as you did all matters that are prohibited while assuming the state of Ihraam out of ignorance, there is no harm, as the one who does any prohibited matter without knowing does not bear any sin. Allaah The Almighty Says (what means):
As for the prohibitions that Allaah The Almighty forbade for the one who assumes the state of Ihraam, if they were done because of forgetfulness or ignorance, the person would bear no sin, but he should give up what he is doing as soon as he realizes or remembers."
