Imām Ibn al-Jawzī (d. 597/1201) summarized the scholars' opinions in his book "Zād al-Masīr" as follows:

1. Shawwal, Dhul-Qa'dah, and the first ten days of Dhul-Hijjah. [Ibn Masʿūd, Ibn ʿUmar, Ibn ʿAbbās, Ibn al-Zubayr, al-Ḥasan, Ibn Sīrīn, ʿAṭāʾ, al-Shaʿbī, Ṭāwūs, al-Nakhaʿī, Qatādah, Makḥūl, al-Ḍaḥḥāk, al-Suddī, Abū Ḥanīfah, Aḥmad ibn Ḥanbal, and al-Shāfiʿī, may Allah have mercy on them] 
2. Shawwal, Dhul-Qa'dah, and the entire month of Dhul-Hijjah. [Also narrated from Ibn ʿUmar, ʿAṭāʾ, Ṭāwūs, Mujāhid, al-Zuhrī, al-Rabīʿ, and Mālik ibn Anas] Ibn Jarīr al-Ṭabarī explained that those who hold the second opinion mean that these months are not for ‘Umrah, but only for Hajj, even though the rituals of Hajj end with the end of the days of Mina (13th Dhul-Hijjah). They preferred to perform ‘Umrah outside these months.

Imām Ibn al-Jawzī (d. 597/1201) summarized the scholars' opinions in his book "Zād al-Masīr" as follows:

1. It refers to intercourse. [Ibn ʿUmar, al-Ḥasan, ʿIkrimah, Mujāhid, Qatādah, and others]
2. It refers to intercourse as well as that which is less that it, such as any suggestive speech related to it. [Also reported from Ibn ʿUmar, Ibn ʿAbbās, ʿAmr ibn Dīnār, and others]
3. It refers to idle talk. [Abū ʿAbd al-Raḥmān al-Yazīdī]

Imām Ibn al-Jawzī (d. 597/1201) summarized the scholars' opinions in his book "Zād al-Masīr" as follows:

1. It refers to cursing. [Ibn ʿUmar, Ibn ʿAbbās, Ibrāhīm]  
2. It refers to name-calling, such as saying to your brother, "O sinner, O oppressor." [Reported by al-Ḍaḥḥāk from Ibn ʿAbbās]  
3. It refers to sins in general. [Al-Ḥasan, ʿAṭāʾ, Ṭāwūs, Mujāhid, Qatādah] Ibn al-Jawzī preferred this opinion.

Imām Ibn al-Jawzī (d. 597/1201) summarized the scholars' opinions in his book "Zād al-Masīr" as follows:

1. It means that no one should argue with another to the extent that it leads to anger and behavior inappropriate for Hajj. [Ibn ʿUmar, Ibn ʿAbbās, Ṭāwūs, ʿAṭāʾ, ʿIkrimah, al-Nakhaʿī, Qatādah, al-Zuhrī, al-Ḍaḥḥāk]
2. It means that there should be no doubt or dispute regarding Hajj, as its rules have been established, its time is known, and any confusion caused by the practice of intercalation has been eliminated. Mujāhid states: They performed Hajj in Dhū al-Ḥijjah for two years, then in Muḥarram for two years, and then in Ṣafar for two years. They performed Hajj in every month for two years until it happened that Abū Bakr's Hajj coincided with the second year of performing Hajj in Dhū al-Qaʿdah, a year before the Prophet's (ﷺ) Hajj. Then the Prophet performed Hajj in the following year in Dhū al-Ḥijjah. It was then that he said, "Time has returned to its original state as it was on the day Allah created the heavens and the earth." (Bukhārī & Muslim) [Al-Suddī from his teachers; al-Qāsim b. Muḥammad]

What is the meaning of "no dispute on/about the Hajj"?
