The Necessity of Washing Between the Fingers

In the Hadith that Humran narrated, `Uthman washed between his fingers when he was describing the Wudu' of the Prophet . The collectors of the Sunan recorded that Laqit bin Sabrah said, "I said, `O Messenger of Allah! Tell me about Wudu'.' The Messenger replied,

« أَسْبِغِ الْوُضُوءَ، وَخَلِّلْ بَيْنَ الْأَصَابِعِ، وَبَالِغْ فِي الِاسْتِنْشَاقِ إِلَّا أَنْ تَكُونَ صَائِمًا »

(Perform Wudu' thoroughly, wash between the fingers and exaggerate in rinsing your nose, unless you are fasting.)''
