The Prophet ﷺ said, "If anyone of you rouses from sleep and performs the ablution, he should wash his nose by putting water in it and then blowing it out thrice, because Satan has stayed in the upper part of his nose all the night." (Using translation from Bukhārī 3295)  

عَنْ رَسُولِ اللهِ ﷺ قَالَ «إِذَا اسْتَيْقَظَ أَحَدُكُمْ مِنْ مَنَامِهِ فَتَوَضَّأَ فَلْيَسْتَنْثِرْ ثَلَاثَ مَرَّاتٍ فَإِنَّ الشَّيْطَانَ يَبِيتُ عَلَى خَيْشُومِهِ»  

The Messenger of Allah ﷺ said: Cleanse your nose well (after snuffing up water) twice or thrice. (Using translation from Abū Dāʾūd 141)   

قَالَ رَسُولُ اللهِ ﷺ «اسْتَنْثِرُوا اثْنَتَيْنِ بَالِغَتَيْنِ أَوْ ثَلَاثًا»
