After having read here and according to the Holy Quran:

until the white thread (light) of dawn appears to you distinct from the black thread (darkness of night) [al-Baqarah 2:187]

I was under the impression that the actual time to take sehri is longer than the Fajr time set in calendar. The Fajr time for my city is 3:28 while sunrise is 05:36. I woke up late (3:40) for my sehri and since I had to also take my medication, I started eating and drinking till 3:58 but just now reading more about it, I realized that this "white thread" described in the Holy Quran is actually twilight not the actual sunrise. I checked it's timing for my city here and it is 3:28. So my question is, was my fast valid? and What should I do if it was not?

    Your fast is not invalidated if: you eat out of forgetfulness; or you mistakenly assume that your fast is broken and you eat after that; or any genuine mistake in understanding and then assuming that your fast is broken. Please continue with your fast. And don't make the same mistake again. HTH. :)

  • In this case, the white thread did not appear distinct to you. So could you really say that your fast was invalidated? :)

  • @Muz I was under the assumption that the white thread referred to the time before sun rise, only to find out it actually referred to twilight time. Jul 10, 2014 at 18:01
  • Its still dark at twilight :) Muz is right. You should go camping one night far from the city and hopefully on a clear night. Wake up just enough at twilight and watch the sky go through the changes. The only people who can see twilight are in the ocean and I think this is why it is called nautical dawn too.

From the view point of most of Ulamas, your fast was broken, but as it wasn't intentional, you shouldn't pay Kafarah(compensation). But you have to take Qaza fast of that day. From this link, this Hukm is an order of Sunnah (Imam Shafei) too. Sorry, if it is in Persian not English.

  • Is this only from scholars of the Shiite Jurisprudence or is the same from Sunnites? Jul 10, 2014 at 17:59


your fast has broken, you will have to make Qadha for it(repay it) after Ramadhaan, and Allah knows Best
