It is fixed with the statement of Holy Quran that namaz (ritual prayer practised by Muslims five times a day in supplication to God) is farz (religious duty obligated for all Muslims) for all believers. There are more than one hundred verses related with this decree in Quran. Each Muslim who will come to this world until the Judgment Day is responsible to fulfill this duty. This responsibility is not limited or bounded with time. That is to say, namaz being farz is not limited with either Hazrath Alis life or anybodys. There is no record that states, Namaz will be performed until Hazrath Alis death as a martyr in our religion, Islam. According to this logic, all of the believers, who will live after Hazrath Ali will not perform namaz, and worship until the Judgment Day. How could it be possible to reflect belief out into the open (in daily lives) then? When there is no such a reflection, how would it be possible to differ to believers from unbelievers?

As you may well know, both Hazrath Omar (as) and Hazrath Osman (as) were massacred as martyrs by rebels (unbelievers) while one was performing his morning namaz in a masjid (place of worship) and the other one was reciting the Holy Quran. There was no one among companions who had stopped going to mosque because of the death of the second and third Caliphs of Islam.

We should also express that headed by Hazrath Hasan (as) and Husayn (as) (Hazrath Alis sons), all believers continued to perform namaz in mosques and read Quran.

Moreover, namaz (except congregational prayers such as Friday prayer and religious feast prayers) is not a prayer, which is bounded by the mosque and the temple. Any place on the earth is a masjid for all Muslims. People who suggest the excuse above can perform namaz in their homes, offices and any place that they like. Nevertheless, if they have left to perform namaz completely, in that case, it is so clear that this excuse is a blind one.
