Now, to ask you your same question, where in the Quran does it say that Maatam should not be done?
Brother
If you wish to do Maatam 24/7 then you should do it bacause you feel for sacrifice of Alhl e bait. But it should be not part of worship of Allah SWT. I do not think it even belongs in Allah's Masjid. When you include it with your Namaaz then it is questionable.
For me I pray 5 (Separate) times a day. I follow Salat timing as per Qur'an and Sunnah. I dress in modest clothes. I do wear suit and tie for my business attire. I read and reflect on Qur'an as much as possible. I should fast but I cannot due to health reasons. I enjoy all modern convinces.
I follow 5 pillars and beliefs that have been precisely stated in Al-Imanul Mufassal, the faith in detail:
Amantu Billahi, Wa Malaikathi, wa Kutubih, wa Rusulihi, wal Yawmil Akhiri, wal Qadri, Khairihi wa Sharrahi minal Lahi Taala, Wal Bathi Badal Mawt.
That means:
I believe in Allah, in His Angels, in His Books, in His messengers, in Last day (Day of Judgment) and in the fact everything good or bad is decided by Allah, the Almighty, and in Life after death.
Here is what Murad Hoffmana former German diplomat writes in his book “Islam the Alternative”
A Muslim lives in a world without clergy and without religious hierarchy; when he prays he does not pray via Jesus, Mary or other interceding saints, but directly to God-as fully emancipated believer-and this in a religion free of mysteries. An atmosphere of this kind suits the modern democratic citizen come of age far better than the wondrous, mystery stricken atmosphere of Byzantine and Catholic Churches, geared towards “Intercession” and focusing sacraments administered by clergymen.
