Allah Almighty says: {Allah wants ease for you and does not want hardship for you.} [Surat al-Baqarah: 185] Allah Almighty also says: {and He has not imposed upon you any hardship in religion.} [Surat al-Hajj: 78] This clearly manifests the facilitation of things for people and the removal of hardship from them during the rituals of Hajj. In this Hadīth, the Tābi‘i Tāwūs ibn Kaysān informs that he was with the Companion ‘Abdullāh ibn ‘Abbās (may Allah be pleased with him) when Zayd ibn Thābit (may Allah be pleased with him) said to him: You issued a Fatwa that a menstruating woman may leave Makkah without performing the Farewell Tawāf! Ibn ‘Abbās replied to him, saying: "If not" i.e., if you do not accept my view, then leave it and go ask the Ansāri woman so-and-so - this is ’Umm Sulaym bint Milhān (may Allah be pleased with her) - as to whether the Messenger of Allah (may Allah's peace and blessings be upon him) enjoined her to do that. So, Zayd (may Allah be pleased with him) went and asked her, and she agreed with the view of Ibn ‘Abbās (may Allah be pleased with him). It is narrated in the Two Sahīh Collections that ‘Ā’ishah, the Prophet's wife, reported that Safiyyah bint Huyay, the Prophet's wife, got her menses during the Farewell Hajj. Thereupon, the Prophet (may Allah's peace and blessings be upon him) said: "Will she delay us?!" I said: "O Messenger of Allah, she has performed the Ifādah Tawāf around the House." Thereupon, the Prophet (may Allah's peace and blessings be upon him) said: "Then, let her depart." When Zayd ibn Thābit (may Allah be pleased with him) knew the right thing, he went back to Ibn ‘Abbās (may Allah be pleased with him), laughing, as he found his view to be correct. Then, he said: "I only found that you spoke the truth." So, Zayd (may Allah be pleased with him) agreed with the view adopted by Ibn' Abbās (may Allah be pleased with him). This is what we are required to do when a dispute arises over something; we should refer to the Qur'an and the Sunnah, and when a sincere person finds proof that disproves his own opinion, he complies with it and scraps stubbornness. The Hadīth shows the politeness of the Companions (may Allah be pleased with them), their righteousness, their keenness to follow the Sunnah, and their readiness to go back to what is right when it becomes manifest. It indicates that if a woman gets her menses, she can depart and leave the Farewell Tawāf. It also demonstrates that some rulings may be unknown to some scholars..
