Ruling on placing amulets containing words from the Qur’an or du‘aa’ around children’s necks
Question

                i was given this Proof of Wearing the tawiz

Hafiz Ibn Kathir and Qadi Shawkani write:

"Amr ibn Shuaib (may Allah be pleased with him) said that Rasulu'llah(may Allah bless him and grant him peace) taught my father and grandfather a du'a which we would read before going to sleep, to protect us from fear and anguish.We told our elder children to recite this du'a before going to sleep as well.But for those children who were not yet literate, we would write it and then put it around their necks"

[Musnad Ahmad ibn Hanbal vol.2; Abu Dawud, in 'Chapter of Medicine'; Tafsir Ibn Kathir, under Sura al-Mu'minun, verse 97; and Qadi Shawkani, Fath al-Qadir, under the same verse]. can you please explain this.
Praise be to Allah.
    Firstly: 

    The hadeeth referred to was narrated by Abu 
    Dawood (3893), at-Tirmidhi (3528), Ahmad in al-Musnad (6696) and 
    others via Muhammad ibn Ishaaq from ‘Amr ibn Shu‘ayb, from his father, from 
    his grandfather, that the Messenger of Allah (blessings and peace of Allah 
    be upon him) said: “If one of you wakes up in alarm, let him say: A‘oodhu bi 
    kalimaat-illaah il-taammaati min ghadabihi wa ‘iqaabihi wa sharri ‘ibaadihi 
    wa min hamazaat al-shayaateeni wa an yahduroon (I seek refuge in the perfect 
    words of Allah from His wrath and His punishment and from the evil of His 
    slaves and from the evil promptings of the devils and from their presence)’, 
    for then they will never be able to harm him.” ‘Abdullah ibn ‘Amr used to 
    teach these words to those of his children who reached puberty, and for 
    those who had not reached puberty he would write them down then hang it 
    around their necks. 

    There are some reservations about this 
    isnaad of this hadeeth, because it is one of the reports narrated by 
    Muhammad ibn Ishaaq, who is mudallis (i.e., he used vague words in order to 
    give a false impression) and he narrated by saying ‘an (“from”, instead of 
    “I heard” and so on). 

    At-Tirmidhi said: This is a hasan ghareeb 
    hadeeth. 

    Ash-Shawkaani said in Fath al-Qadeer 
    (3588): Its isnaad includes Muhammad ibn Ishaaq, concerning whom the 
    scholarly opinions are well known. 

    Al-Albaani said: It is hasan apart from the 
    words “‘Abdullah ibn ‘Amr used to teach these words…” Saheeh 
    at-Tirmidhi (3528). See also as-Silsilah as-Saheehah (1/529); 
    at-Ta‘leeq ‘ala Musnad Ahmad, ar-Risaalah edition (11/296); an-Nahj 
    as-Sadeed by ad-Dawsari, no. 111. 

    Based on that, what is narrated about 
    ‘Abdullah ibn ‘Amr (may Allah be pleased with him) hanging this supplication 
    around the necks of his children is not correct, because the isnaad of this 
    addition to the hadeeth is not saheeh. 

    Secondly: 

    With regard to the use of amulets and 
    ta’weez [also spelled ta’wiz, taveez, etc], if it contains words from the 
    Qur’an or du‘aa’ (supplication), then there is a difference of scholarly 
    opinion concerning that, as to whether it is disallowed or permitted. 

    Undoubtedly disallowing that is a means of 
    preventing objectionable beliefs, especially nowadays. If it was regarded as 
    makrooh (disliked) by most of the earlier generations, even though their 
    time was further removed from innovations, misguidance and polytheistic 
    beliefs, and was closer to the light of revelation and faith, then in times 
    such as our own, when ignorance and innovation are widespread, disallowing 
    it is more appropriate.
