What is the proof for the permissibility of wearing the hirz (i.e. certain inscriptions of ayahs and/or specific religious phrases), which is unlike the artifacts that contain certain forbidden talismanic characters?
Suratul-Isra’, Ayah 82 means, “Allah sends down ayat from the Qur’an in which there is healing and mercy.” It is also narrated that the great companion, ^Abdullah Ibn ^Amr said, “We taught our kids to recite specific words that help gain protection by the will of Allah and for those who had not reached puberty we inscribed these words on paper and hung them (around their necks) on their chests.” (Related by at-Tirmidhiyy.)
