بِسْمِ اللّٰهِ الرَّحْمٰنِ الرَّحِيْمِ
وَقُل رَّبِّ أَعُوذُ بِكَ مِنْ هَمَزَاتِ الشَّيَاطِينِ ﴿٩٧﴾ وَأَعُوذُ بِكَ رَبِّ أَن يَحْضُرُونِ ﴿٩٨﴾
And say, ` 0 my Lord, I seek your refuge from the strokes of the Shaytaan, and I seek Your refuge from that they come to me.’ (23:97, 98)
The word هَمَز (the infinitive of هَمَزَاتِ Hamazat translated above as ‘strokes’ ) means “to push, to press” and sometimes is also used to mean “to make a call from behind”. This is a very comprehensive prayer often invoked for protection from the guile and mischief of Shaytaan and the Rasulullah Sallallahu Alayhi Wasallam has urged upon the Muslims to recite it frequently in order to avoid sudden bursts of rage which are brought about by the promptings of Shaytaan and which cause people to lose self-control. This prayer is also very effective in repelling other assaults of Shayateen and Jinn.
Sayyidna Khalid Radiallahu Anhu suffered from insomnia and Rasulullah Sallallahu Alayhi Wasallam suggested that he should recite the following prayer before going to bed:
اَعُوذ بِکَلِمَاتِ اللہِ التَّامَّۃِ مِن غضَبِ اللہِ وَعِقَابِہٖ وَمِن شَرِّ عِبَادِہٖ وَمِن ھَمَزٰتِ الشَّیٰطِینِ وَاَن یَّحضُرُونِ
I seek refuge with Allah’s Perfect Words from Allah’s wrath and His punishment, and from the evils of His slaves, and from the promptings of the Shayateen and from that they come to me.
Sayyidna Khalid Radiallahu Anhudid as advised and was soon cured of insomnia.
According to a Hadith in Sahih of Muslim Rasulullah Sallallahu Alayhi Wasallam is reported to have said that Shaytaan meddles in all human affairs and tempts people to do evil deeds, and that this prayer is the best protection against his attempts. (Qurtubi)
