حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا يَحْيَى بْنُ سُلَيْمٍ الطَّائِفِيُّ، عَنْ إِسْمَاعِيلَ بْنِ كَثِيرٍ، عَنْ عَاصِمِ بْنِ لَقِيطِ بْنِ صَبِرَةَ، عَنْ أَبِيهِ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ أَسْبِغِ الْوُضُوءَ وَخَلِّلْ بَيْنَ الأَصَابِعِ .
'Asim bin Laqit bin Saabirah narrated that his father said: "The Messenger of Allah said: perform ablution properly and let the water run between your fingers."
