Do lancing devices invalidate wudū’?


AssalamuAlaikum. I have a question. When I prick my finger with the diabetes thing to check my sugar levels and it bleeds a tiny bit does my Wudu break? Cuz I can easily make wudu when I’m home but when I’m out it gets a little difficult.


In the Name of Allah, the Most Gracious, the Most Merciful.

As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.

In principle, if blood spreads beyond a wound, it is flowing blood which invalidates wudhū’. Accordingly, wudhū’ will have to be renewed.[i] When using a lancing device, blood flows beyond the wound necessitating renewal of wudhū’.

And Allah Ta’āla Knows Best

مختصر القدوري (ص: 11(

كل ما خرج من السبيلين والدم والقيح والصديد إذا خرج من البدن فتجاوز إلى موضع يلحقه حكم التطهير


المبسوط للسرخسي (1/ 76(

قال (وإن خرج من جرحه دم، أو صديد، أو قيح فسال عن رأس الجرح نقض الوضوء عندنا)


فتح القدير للكمال ابن الهمام (1/ 39(

الخروج في غير السبيلين هو تجاوز النجاسة إلى موضع التطهير، فالمعنى إذا خرجا بأن تجاوزا إلا أن يحمل الخروج على الظهور فليس به، والمعنى إذا ظهرا فتجاوز
