Narrated Aqra’ ibn Habib (RA): Ibn Abbas said: Aqra’ ibn Habis (RA) asked the Prophet (peace be upon him) saying: Messenger of Allah hajj is to be performed annually or only once? He replied: Only once, and if anyone performs it more often, he performs a supererogatory act. Abu Dawud said: The narrator Abu Sinan is Abu Sinan al-Du’wail. The same has been reported by both ‘Abd al-Jalil bin Humaid and Sulaiman bin Kathir from al-Zuhri. The narrator ‘Uqail reported the name “Sinan”.
