It contains du’as, supplications, Ziyarahs, practices specific to certain days, months, and occasions, religious practices and manners, as well as some anecdotes narrated from the Prophet (s), Imams (a), and Islamic scholars.

Index of Mafatih al-Jahim (‘al-Jinan’): Translation (highlighted yellow part):

The virtue of the day of Nowruz and the recommended religious rituals on that day and on the Roman months.

Translation of the red-marked part:

As for the recommended religious rituals on Nowruz, it is what [Imam] Sadiq (peace be upon him) taught Mu’alla ibn Khunays, who said: “Take a Ghusl on the day of Nowruz and put on clean and new clothes and apply perfume, and fast on that day. After your nafilah, Dhuhr, and ‘Asr prayers, pray four units separated by two salams. Read in the first unit Surah Al-Fatihah and ten times Surah Al-Qadr, and in the second unit read Surah Al-Fatihah and ten times Surah Al-Kafirun. In the third unit, read Al-Fatiha and ten times Surah Al-Ikhlas. In the fourth unit, read Al-Fatihah and ten times Surahs Al-Falaq and An-Nas. Finally, after finishing the unit, prostrate and say the following du’a (supplication)…”

Qommi’s promise to Shias at the end of this chapter:

يغفر لك ذنوب خمسين سنة

“Your sins of fifty years will be forgiven”

Comment: 

So Tarawih is an evil bid’ah, but revering a Majoosi eid in the name of Ahlul-Bayt (peace be upon him) is totally legit and a Sunnah?! Did the Prophet (ﷺ) take Nowruz as a day of eid? You don’t need to be an Einstein to see the contradiction and double standards in Shiism and by those who advocate it.

Now, decades later, comes another ‘Ayatollah’ (mini dajjal) called Makarem Shirazi (who doesn’t even know how to recite the Fatihah correctly) with a book called ‘Mafatih Novin’, which is basically a modified version of ‘Mafatih al-Jinan’. Makarem’s goal, as he mentioned in the preface of the book, has been to make the book well-suited to the current time and remove some content over which there have been disagreements. You’d think he removed absurd claims such as the veneration of Majoosi Nowruz (and other blatant kufr and shirk such as beseeching Fatimah hundreds of times for help in your prostration, or visiting the cellar of the Shia Mahdi and beseeching him for help and other bizarre absurdities). Well, of course, he didn’t. The fourth chapter of his version of Mafatih includes the practices of the solar months such as Nowruz. In fact, he goes as far as to claim that Nowruz has Islamic significance.

…he [‘Ayatollah’ Makarem Shirazi] states that this day (i.e. Nowruz) has Islamic significance, which we need to ensure is marked in an Islamic fashion.
