Protect your prayer times before the day gets crowded

Arihna Biha protects prayer time in your Google or Outlook calendar and adapts automatically when your schedule changes.

حَدَّثَنَا مُسَدَّدٌ، قَالَ حَدَّثَنَا إِسْمَاعِيلُ بْنُ إِبْرَاهِيمَ، قَالَ أَخْبَرَنَا ابْنُ جُرَيْجٍ، قَالَ أَخْبَرَنِي عَطَاءٌ، أَنَّهُ سَمِعَ أَبَا هُرَيْرَةَ ـ رضى الله عنه ـ يَقُولُ فِي كُلِّ صَلاَةٍ يُقْرَأُ، فَمَا أَسْمَعَنَا رَسُولُ اللَّهِ صلى الله عليه وسلم أَسْمَعْنَاكُمْ، وَمَا أَخْفَى عَنَّا أَخْفَيْنَا عَنْكُمْ، وَإِنْ لَمْ تَزِدْ عَلَى أُمِّ الْقُرْآنِ أَجْزَأَتْ، وَإِنْ زِدْتَ فَهُوَ خَيْرٌ‏.‏

Narrated Abu Huraira: The Qur'an is recited in every prayer and in those prayers in which Allah's Messenger (ﷺ) recited aloud for us, we recite aloud in the same prayers for you; and the prayers in which the Prophet (ﷺ) recited quietly, we recite quietly. If you recite "Al-Fatiha" only it is sufficient but if you recite something else in addition, it is better.

Why this exists

This started with a simple frustration: back-to-back meetings kept swallowing Dhuhr, Asr, and Maghrib before I noticed the day had moved on.

Praying on time is not a two-minute context switch. Sometimes it means walking to a nearby mosque, performing wudu, and taking a few quiet minutes to arrive with presence.

That is why Arihna Biha does not just mark the prayer time. It creates a real protected window, with a buffer that respects the shape of the day around it.

I built it for myself first, then shared it so others could make room for prayer without fighting their calendar every day.
