As-Salāmu `Alaykum (السلام عليكم):
I didn't want to ruin the beautiful thread created by 'Abd-al Latif The Official Ramadan Thread. Ramadan 1431 A.H/August 2010 because this thread included a question and that thread provides more of a how to fast.
The Suhur is a light pre-dawn meal eaten no later than ten minutes before Fajr. (My lifetime practice)
That being understood is there anyone that has a different practice?
Has anyone experienced Muslims eating or drinking after fajr prayer? Now keep in mind what is in the Quran. I always understood that as a guide to the latest time frame to eat suhur as if someone woke up late, etc.
My practice is once the intention is made for fasting, eats suhur, performs fajr salat, the fast begins.
Surah Al Baqarah 2:187
187. It is made lawful for you to have sexual relations with your wives on the night of As-Saum (the fasts). They are Libas [i.e. body cover, or screen, or Sakan, (i.e. you enjoy the pleasure of living with her - as in Verse 7:189) Tafsir At-Tabari], for you and you are the same for them. Allah knows that you used to deceive yourselves, so He turned to you (accepted your repentance) and forgave you. So now have sexual relations with them and seek that which Allah has ordained for you (offspring), and eat and drink until the white thread (light) of dawn appears to you distinct from the black thread (darkness of night),
then complete your Saum (fast) till the nightfall. And do not have sexual relations with them (your wives) while you are in I'tikaf (i.e. confining oneself in a mosque for prayers and invocations leaving the worldly activities) in the mosques. These are the limits (set) by Allah, so approach them not. Thus does Allah make clear His Ayat (proofs, evidences, lessons, signs, revelations, verses, laws, legal and illegal things, Allah's set limits, orders, etc.) to mankind that they may become Al-Muttaqun (the pious - see V.2:2).
(Muhammad Muhsin Khan translation)
That is why I didn't include it in the official thread.
