Sunnah embodies tawhid

It was narrated from Abu Hurayrah, may Allah be pleased with him, who said: “A man came to the Prophet, peace and blessings of Allah be upon him, and said: “O Messenger of Allah, if you knew what I suffered from a scorpion that last night stung me!” On this, the Prophet, peace and blessings of Allah be upon him, said to him: “If in the evening you said:“ I seek protection from the perfect words of Allah from the evil of what He created, ”the scorpion would not hurt you!”

أعوذ بكلمات الله التامات من شر ما خلق

A’uzu bi-kyalimati Llahi-t-tammati min sharri ma halyak / ( These words should be pronounced once in the evening).

Suhail, one of the transmitters of this hadith, said: “Our relatives memorized these words and uttered them every evening, and when one girl from among them was stung, she did not feel pain.”
See Muslim 2709,

It is reported that Hawla bint Hakim said that she heard the Prophet (peace and blessings of Allaah be upon him) say: that is created by Him!” – no harm will come while he is in this place ”

أعوذ بكلمات الله التامات من شر ما خلق

Muslim 2708

Sheikh ‘Abdur-Razzaq al-Badr (may Allah preserve him) said: “The words: ‘the perfect words of Allah’ means that His words are absolutely perfect and completely devoid of flaws, regardless of whether by ‘words of Allah’ His orders are meant in the Universe, which is referred to in the words of the Almighty (semantic translation): “When He desires something, then He should say: “Be!” – how it comes true” (36:82),

or they mean His words in religious institutions, like the Noble Qur’an – “Verily, this is a mighty Scripture. Lies will not get to him either in front or behind. It is sent down from the Wise, the Praiseworthy” (41:41-42)

In any case, the words of Allah are perfect and there is no flaw in them in any respect.”
