salam for all, please Nour ali, give us the verses refering to 3 prayers in quran, i see only 2, the fajr and the icha, as for the isha it ends at dusk, see 24:58, ......after salat al isha...., simply indicate that the time of isha has an end.
for amazigh, ame very happy to see an amazigh in free-minds, God willing you will find the reel way to pray within the quran, trust God He is the best teacher. i direct you to download the tool of research: www.zekr.org
the winqt2.exe at submission.org.
peace up on who follow the guidance.
