Is it permissible to recite the Ruqya Shar'iyyah collectively into Zamzam water, and is repeating the verses three times a Sunnah, and is it obligatory to repeat the recitation daily?

It is mentioned in Sahih Muslim and elsewhere that Jibril (Gabriel) performed Ruqyah (spiritual healing) on the Prophet, peace and blessings be upon him, by saying: "In the name of Allah I perform Ruqyah on you, from everything that harms you..." There is no harm in changing the wording of the supplication from the singular to the plural. Sufficing with reading the supplication once is permissible, except for the second supplication which is read seven times while placing the hand on the site of the pain. As for the Quranic verses used for Ruqyah, it has not been proven that their recitation is limited to a specific number, and the Ruqyah can be repeated until healing occurs.
