Ruqyah for the sick must be done directly, not via a loudspeaker or over the phone, because this is contrary to the way the Prophet (peace and blessings of Allaah be upon him), his companions (may Allaah be pleased with them) and those who followed them in truth did ruqyah. The Prophet (peace and blessings of Allaah be upon him) said: “Whoever innovates something in this matter of ours (i.e., Islam) that is not a part of it, will have it rejected.”
And Allaah knows best.
[Translator’s note: ruqyah i.e., reciting Qur’aan and du’aa’s over the sick for the purpose of seeking healing]
