If One Overslept for Sehri and Was Using the CPAP With a Humidifier

Answered as per Hanafi Fiqh by DarulIftaBirmingham

Answered by: Alimah Zainab Nakhuda


If one overslept for sehri and was using the CPAP with a humidifier.  What’s the status of fast?

In the name of Allah, the Most Gracious, the Most Merciful


A CPAP (Continuous positive airway pressure) machine is used by those suffering from obstructive sleep apnea (a condition where sometimes the airways have the risk of collapsing whilst sleeping, obstructing the person’s breathing). It assists the airways to stay open whilst the person sleeps by providing pressurized air.1 A humidifier is a device that releases water vapour or steam to increase moisture levels in the air (humidity).2

Because this water vapour is going through and past the throat, it will break the fast as the water is being consumed in this sense; the fast will no longer be valid.3

Only Allah knows best.

وَأَمَّا رُكْنُهُ: فَالْإِمْسَاكُ عَنْ الْأَكْلِ، وَالشُّرْبِ، وَالْجِمَاعِ … فَدَلَّ أَنَّ رُكْنَ الصَّوْمِ مَا قُلْنَا فَلَا يُوجَدُ الصَّوْمُ بِدُونِهِ.

وَعَلَى هَذَا الْأَصْلِ يَنْبَنِي بَيَانُ مَا يُفْسِدُ الصَّوْمَ وَيَنْقُضُهُ لِأَنَّ انْتِقَاضَ الشَّيْءِ عِنْدَ فَوَاتِ رُكْنِهِ أَمْرٌ ضَرُورِيٌّ، وَذَلِكَ بِالْأَكْلِ، وَالشُّرْبِ، وَالْجِمَاعِ سَوَاءٌ كَانَ صُورَةً وَمَعْنًى، أَوْ صُورَةً لَا مَعْنًى، أَوْ مَعْنًى لَا صُورَةً وَسَوَاءٌ كَانَ بِغَيْرِ عُذْرٍ، أَوْ بِعُذْرٍ وَسَوَاءٌ كَانَ عَمْدًا، أَوْ خَطَأً طَوْعًا، أَوْ كَرْهًا بَعْدَ أَنْ كَانَ ذَاكِرًا لِصَوْمِهِ لَا نَاسِيًا وَلَا فِي مَعْنَى النَّاسِي،،
