Is it permissible for someone to supplicate aloud for the sick so that those present may say "Ameen" after him?

Praying for the sick is among the recommended manners of visiting them, and it was the guidance of the Prophet, peace and blessings be upon him. It is authentically reported that he used to pray for the sick and encouraged others to do so, teaching us the form of supplication through which a response is hoped for. It is recommended for the visitor to pray for the sick, whether individually or in a group. There is no harm if one of them supplicates and the rest say "Ameen," because saying "Ameen" to a supplication is itself a supplication, and by this, the Sunnah is fulfilled for everyone.
