The following hadeeth :
(كان إذا أوى إلى فِراشهِ كلَّ ليلةٍ جمَعَ كفَّيهِ ، ثم نفَثَ فيهما، فقرأ فيهما(قل هو الله أحد) و (قل أعوذ برب الفلق) و ( قل أعوذ برب الناس) ، ثم يمسح بهما ما استطاع من جسده، يبدأُ بهما على رأسهِ ووجههِ ، وما أقبل من جسده ، يفعل ذلك ثلاث مرات ) .
أخرجه البخاري (5017)،
Aa’ishah (may Allaah be pleased with her) reported that when the Prophet (peace and blessings of Allaah be upon him) went to bed each night, he would put his palms together, blow in them, then would recite Qul huwa Allaahu ahad, Qul a’oodhu bi Rabbi’l-Falaq and Qul a’oodhu bi Rabbi’l-Naas, then he would wipe as much of his body as he could with his hands, starting with his head and face, and the front of his body, doing this three times.
[Reported by Al-Bukhari].
Some of the scholars use this narration to prove that it is also legislated to start with the act of blowing into the palms before the reading.
Ash-Shaykh Muhammad bin Saalih al-Uthaymeen, rahimahullah, mentiioned that both are legislated and that the person has a choice of either starting with the act of reading or the act of blowing in the palms although what is more apparent to him is starting with the act of blowing into the palms first.
Also Ash-Shaykh Albany, rahimahullah, was asked the following question:
Is the recitation first or the blowing into the hands?
What is first is the blowing into the palms then the reading then wiping over one’s body.
Some of the other scholars have combined between the above hadeeth and the hadeeths which indicate that the blowing comes after the reading by saying that the act of blowing into the palms comes first when done for الوقاية (i.e. protection) and the act of reading comes first before blowing when done for الإصابة (i.e. Affliction). And Allah knows best.
