He moved them (his hands) for wiping to the front of his head and then the nape of his neck, then bringing them back till he reached the place from which he had begun, after which he washed his feet.  

وَقَالَ مَضْمَضَ وَاسْتَنْثَرَ ثَلاَثًا وَلَمْ يَقُلْ مِنْ كَفٍّ وَاحِدَةٍ وَزَادَ بَعْدَ قَوْلِهِ فَأَقْبَلَ بِهِمَا وَأَدْبَرَ بَدَأَ بِمُقَدَّمِ رَأْسِهِ ثُمَّ ذَهَبَ بِهِمَا إِلَى قَفَاهُ ثُمَّ رَدَّهُمَا حَتَّى رَجَعَ إِلَى الْمَكَانِ الَّذِي بَدَأَ مِنْهُ وَغَسَلَ رِجْلَيْهِ  

"Messenger of Allah wiped over his head with his hands, going over the front with them and the rear. He began with the front of his head until they went to the nape of his neck. Then he brought them back again to the place where he began. Then he washed his feet."  

أَنَّ رَسُولَ اللَّهِ ﷺ مَسَحَ رَأْسَهُ بِيَدَيْهِ فَأَقْبَلَ بِهِمَا وَأَدْبَرَ بَدَأَ بِمُقَدَّمِ رَأْسِهِ ثُمَّ ذَهَبَ بِهِمَا إِلَى قَفَاهُ ثُمَّ رَدَّهُمَا حَتَّى رَجَعَ إِلَى الْمَكَانِ الَّذِي بَدَأَ مِنْهُ ثُمَّ غَسَلَ رِجْلَيْهِ
