There will be a Total Lunar Eclipse on 28 August 2007 Tuesday morning between 1:51am and 5:24am

For a view of the places affected please visit: the Nasa web site.

It is wajib to pray namaz-e-Ayat during the eclipse, and since we in North America will witness a total eclipse, qaza is wajib even for those who did not know at the time.

Namaz-e-Ayaat can be offered in the following manner:
After making niyyat to offer Namaz-e-Ayaat, a person is allowed to say takbir and recite Surah al-Hamd and then divide the verses of the other Surah into five parts, and recite one verse or more or less, and thereafter perform the Ruku. He should then stand up and recite another part of the Surah (without reciting Surah al-Hamd) and then perform another Ruku. He should repeat this action, and finish that Surah before performing the fifth Ruku. For example, he may say: Bismillahir Rahmanir Rahim with the niyyat of reciting Surah al-Ikhlas, and perform the Ruku. He should then stand up and say, Qul huwallahu Ahad, and perform another Ruku. He should then stand up and say, Allahus Samad, and perform the third Ruku. Thereafter he should stand up again and say, Lam yalid walam yulad, and perform the fourth Ruku. Then he should stand up again and say, Walam yakullahu Kufuwan ahad, and then perform two Sajdah and then rise for the second Rak'at, the same way as the first Rak'at. At the end, he should recite tashahhud and Salam after the two Sajdah.
