A number of devotional acts may be practiced on this blessed day:
First: It is recommended to observe fasting on this day, for its reward is equal to the reward of eighty-month worship.
Second: It is recommended to offer a two unit prayer half an hour before midday. At each unit, Surah al-Faatehah is recited once and Surah al-Tawheed, Ayah al-Kursi, and Surah al-Qadr repeated ten times each.
It is recommended to offer Salat Fatimah. According to Shaykh al-Tusi, this prayer consists of four units each couple of which are offered separately. At each unit, Surah al-Faatehah is recited once and Surah al-Tawheed repeated fifty times. After the Taslim statement, the famous Tasbih al-Zahra’ litany is done. Thereafter, the following doxology is said:
سُبْحَانَ ذِی الْعِزِّ الشَّامِخِ الْمُنِیْفِ سُبْحَانَ ذِی الْجَلَالِ الْبَاذِخِ الْعَظِیْمِ سُبْحَانَ ذِی الْمُلْکِ الْفَاخِرِ الْقَدِیْمِ سُبْحَانَ مَنْ یَّرٰی اَثَرَ النَّمْلَۃِ فِی الصَّفَا سُبْحَانَ مَنْ یَّرٰی وَقُعَ الطَّیْرِ فِی الْھَوَآئِ سُبْحَانَ مَنْ ھُوَ ھٰکَذَا وَلَا ھٰکَذَا غَیْرُہٗ
Glory be to the Lord of Honor and Sublime Authority. Glory be to the Lord of Majesty and Exalted Greatness. Glory be to the Lord of eternal, splendid sovereignty. Glory be to Him Who makes out the footprints of the ant on the stone. Glory be to Him Who knows the exact time and place of the bird dipping down through the air. Glory be to Him Who is like this and no one other than Him is like this.
One who fears an oppressor and says the following words on this day will be saved, by Almighty Allah:
حَسْبِیْ حَسْبِیْ حَسْبِیْ مِنْ سُوَالِیْ عِلْمُکَ بِحَالِیْ
My circumstances under which i have made a request to thee are already in thy knowledge covering every aspect more thoroughly than what i am aware of ,and it is more than enough for me.
On this day according to the narration of the two Shaykhs, Imam AliAmeer al-Momineen(a.s.) married Lady Fatimah al-Zahra’(a.s.).
