String Over Which Verses of Quran Have Been Recited
Question

Is it permissible to recite the Quran over a piece of string etc, and tie that over a child's wrist to protect him from the evil eye or other diseases?
Alternatively, is it permissible to place Quranic ayah (verse) in a small metal capsule and tie it over the wrist of Muslims to serve as protection from the evil eye or mishaps?
People in my community do both of these very frequently. They get the local masjid imam to provide the service. I do not want to do this for my child unless there is a sound basis for it in the Shari'ah (Islamic law).
Please help me find out the truth.
Praise be to Allah.It is not permissible to tie this string or any other kind of amulets. The Prophet (peace and blessings of Allah be upon him) said: “Whoever hangs up an amulet, may Allah not fulfill his need.”
And he said: “Whoever hangs up anything will be abandoned to its care,” and, “Whoever hangs up an amulet has committed shirk.”  
The Prophet (peace and blessings of Allah be upon him) commanded us to tear away these things, as stated in the hadeeth (narration) narrated from ‘Imran ibn Husayn, which says that the Prophet (peace and blessings of Allah be upon him) saw a man on whose hand was a bracelet of brass. He said, “What is this bracelet?” He said, “It is to prevent weakness.” He said, “Take it off, for it will only make you more weak.” This was narrated by Ibn Majah.
