Full Sharh — Riyad as-Salihin 564
وعن لقيط بن صبرة رضي الله عنه قال قلت يا رسول الله أخبرني عن الوضوء؟ قال" "أسبغ الوضوء، وخلل بين الأصابع، وبالغ في الاستنشاق، إلا أن تكون صائمًا" ((رواه أبوداود، والترمذي وقال: حديث حسن صحيح)).
English Translation
Laqit bin Sabirah (May Allah be pleased with him) reported:: I requested the Messenger of Allah (ﷺ) to talk to me about ablution. He said, "Perform the Wudu' well (by washing those parts of the body, such as the face, hands and feet beyond what is required, like washing the hands up to the upper-arm instead of the elbow). Cleanse the base of your fingers and sniff water deep into the nose except when you are observing fast.".
