From his father who said: "I said. 'O Messenger of Allah! Inform me about Wudu.' So he said: "Perform Wudu well, and go between the fingers, and perform Istinshaq extensively except when fasting." (Using translation from Tirmidhī 788)
" أسْبِغْ الوضوءَ، وخلِّلْ بين الأصابعِ، وبالغْ في الاستنشاق إلا أن تكون صائمًا".
