About this blessed day, Shaykh al-Tusi says in Misbah al-Mutahajjid: Imam al-Husayn ibn Ali(a.s.) was born on the third of Sha’ban. Abu’l-Qasim ibn ‘Ala’ al-Hamadani, the representative of Imam al-Hasan al-’Askari(a.s.), received a document telling that our master, Imam al-Husayn ibn Ali(a.s.), was born on the third of Sha’ban; therefore, you should observe fasting on this day and say the following supplicatory prayer:
اَللّٰھُمَّ اِنِّیْٓ اَسْئَلُکَ بِحَقِّ الْمَوْلُوْدِ فِیْ ھٰذَا الْیَوْمِ الْمَوْعُوْدِ بِشَہَادَتِہِ قَبْلَ اسْتِھْلَالِہٖ وَوِلَادَتِہٖ بَکَتْہُ السَّمَآئُ وَمَنْ فِیْہَا وَالْاَرْضُ وَمَنْ عَلَیْہَا وَلَمَّا یَطَاْ لابَتَیْہَا قَتِیْلِ الْعَبْرَۃِ وَسَیِّدِ الْاُسْرَۃِ الْمَمْدُوْدِ بِالنُّصْرَۃِ یَوْمَ الْکَرَّۃِ الْمُعَوَّضِ مِنْ قَتْلِہٖٓ اَنَّ الْاَئِمَّۃَ مِنْ نَسْلِہٖ وَالشِّفَآئَ فِیْ تُرْبَتِہٖ وَالْفَوْزَ مَعَہُ فِی اَوْبَتِہٖ وَالْاَوْصِیَآئَ مِنْ عِتْرَتِہٖ بَعْدَ قَآئِمِھِمْ وَغَیْبَتِہٖ حَتّٰی یُدْرِکُوا الْاَوْتَارَ وَیَثْاَرُوا الثَّارَ وَیُرْضُوا الْجَبَّارَ وَیَکُوْنُوْا خَیْرَ اَنْصَارٍ صَلَّی اللّٰهُ عَلَیْھِمْ مَعَ اخْتِلَافِ اللَّیْلِ وَالنَّھَارِ اَللّٰھُمَّ فَبِحَقِّھِمْ اِلَیْکَ اَ تَوَسَّلُ وَاَسْئَلُ سُؤَالَ مُقْتَرِفٍ مُعْتَرِفٍ مُسِٓیْیءٍ اِلٰی نَفْسِہٖ مِمَّا فَرَّطَ فِیْ یَوْمِہٖ وَاَمْسِہٖ یَسْئَلُکَ الْعِصْمَۃَ اِلٰی مَحَلِّ رَمْسِہٖ اَللّٰھُمَّ فَصَلِّ عَلٰی مُحَمَّدٍ وَّعِتْرَتِہٖ وَاحْشُرْنَا فِیْ زُمْرَتِہٖ وَبَوِّئْنَا مَعَہٗ دَارَ الْکَرَامَۃِ وَمَحَلَّ الْاِقَامَۃِ اَللّٰھُمَّ وَکَمَآ اَکْرَمْتَنَا بِمَعْرِفَتِہٖ فَاَکْرِمْنَا بِزُلْفَتِہٖ وَارْزُقْنَا مُرَافَقَتَہٗ وَسَابِقَتَہٗ وَاجْعَلْنَا مِمَّنْ یُّسَلِّمُ لِاَمْرِھٖ وَیُکْثِرُ الصَّلوٰۃَ عَلَیْہِ عِنْدَ ذِکْرِھٖ وَعَلٰی جَمِیْعِ اَوْصِیَآئِہٖ وَاَھْلِ اَصْفِیَآئِہِ الْمَمْدُوْدِیْنَ مِنْکَ بِالْعَدَدِ الْاِثْنَیْ عَشَرَ النُّجُوْمِ الزُّھَرِ وَالْحُجَجِ عَلٰی جَمِیْعِ الْبَشَرِ اَللّٰھُمَّ وَھَبْ لَنَا فِیْ ہٰذَا الْیَوْمِ خَیْرَ مَوْھِبَۃٍ وَّاَ نْجِحْ لَنَا فِیہِ کُلَّ طَلِبَۃٍ کَمَا وَھَبْتَ الْحُسَیْنَ لِمُحَمَّدٍ جَدِّھٖ وَعَاذَ فُطْرُسُ بِمَھْدِھٖ فَنَحْنُ عَآئِذُوْنَ بِقَبْرِھٖ مِنْ بَعْدِھِ نَشْھَدُ تُرْبَتَہٗ وَنَنْتَظِرُ اَوْبَتَہٗٓ اٰمِیْنَ رَبَّ الْعَالَمِیْنَ ۔
O Allah, I beseech You in the name of the one born on this day, the promised with martyrdom before the beginning of his lifetime and before his birth, the heavens and all their inhabitants wept for him; and so did the earth and those living one it before his feet stepped on it, the mourned slain one, the master of the Family (of Prophet hood), the one who shall be backed with victory on the Day of Return, the one whom has been awarded the favor of the Imams’ being from his offspring as recompense of his being slain, the one awarded the favor of the soil of his grave carrying cure, the one awarded the favor that he will be triumphing when he will be returned and the Prophet’s Successors from his offspring will be returned after the advent of their Rising Imam and after his occultation so that they shall take revenge, retaliate, please the Omnipotent Lord, and be the best supporters. May Allah’s blessings be perpetually upon them whenever night and day succeed each other. O Allah, I thus beg You in the name of them and implore You with the imploration of a sinful one who confesses of his sin, and who has done evil to himself due to his violations—the past and the present. He thus beseeches You for Your protection up to the place of his grave. O Allah, (please) send blessings to Muhammad and his Offspring, include us with his group (on the Resurrection Day), and allow us to dwell in the House of Honor with him and in the abode of residence. O Allah, as You have conferred upon us with the honor of our recognition of him, so (please) confer upon us with the honor of being near to him, bestow upon us with the bliss of accompanying him and enjoying a close rank to him, and include us with those who submit to him totally and those who invoke Your blessings upon him whenever they mention him, and upon all his Successors and Selected Ones, whom are defined by You as twelve persons, being the luminous stars, and the Arguments against all humankind. O Allah, and (please) grant us on this day the best of grants, make all our prayers on this day responded, just as You gifted al-Husayn to Muhammad, his grandfather, just as the angel Futrus sought refuge with his (i.e. al-Husayn) cradle, we are thus seeking refuge with his tomb after him (i.e. his martyrdom), as we are witnessing the soil of him and expecting his return. Respond to us, O Lord of the worlds.
After that Above Prayer you may say Dua al-Husayn (Supplicatory prayer of Imam al-Husayn), which is the last supplicatory prayer he said when his enemies surrounded him in large numbers on the Day of ‘Ashura (the tenth of Muharram):
اَللّٰھُمَّ اَ نْتَ مُتَعَالِی الْمَکَانِ عَظِیْمُ الْجَبَرُوْتِ شَدِیْدُ الْمِحَالِ غَنِیٌّ عَنِ الْخَلَآئِقِ عَرِیْضُ الْکِبْرِیَآئِ قَادِرٌ عَلٰی مَا تَشَآئُ قَرِیْبُ الرَّحْمَۃِ صَادِقُ الْوَعْدِ سَابِغُ النِّعْمَۃِ حَسَنُ الْبَلَآئِ قَرِیبٌ اِذَا دُعِیْتَ مُحِیطٌ بِمَا خَلَقْتَ قَابِلُ التَّوْبَۃِ لِمَنْ تَابَ اِلَیْکَ قَادِرٌ عَلٰی مَا اَرَدْتَ وَمُدْرِکٌ مَا طَلَبْتَ وَشَکُوْرٌ اِذَا شُکِرْتَ وَذَ کُوْرٌ اِذَا ذُکِرْتَ اَدْعُوْکَ مُحْتَاجًا وَّاَرْغَبُ اِلَیْکَ فَقِیْرًا وَّاَ فْزَعُ اِلَیْکَ خَآئِفًا وَاَبْکِیْٓ اِلَیْکَ مَکْرُوْبًا وَاَسْتَعِیْنُ بِکَ ضَعِیْفًا وَّاَ تَوَکَّلُ عَلَیْکَ کَافِیًا اُحْکُمْ بَیْنَنَا وَبَیْنَ قَوْمِنَا فَاِ نَّھُمْ غَرُّوْنَا وَخَدَعُوْنَا وَخَذَلُوْنَا وَغَدَرُوْا بِنَا وَقَتَلُوْنَا وَنَحْنُ عِتْرَۃُ نَبِیِّکَ وَوَلَدُ حَبِیْبِکَ مُحَمَّدِ بْنِ عَبْدِاللّٰهِ الَّذِیْ اصْطَفَیْتَہٗ بِالرِّسَالَۃِ وَائْتَمَنْتَہٗ عَلٰی وَحْیِکَ فَاجْعَلْ لَنَا مِنْ اَمْرِنَا فَرَجًا وَّمَخْرَجًا بِرَحْمَتِکَ یَا اَرْحَمَ الرَّاحِمِیْنَ ۔
O Allah, You are verily the Elevated in position, the Magnificent in omnipotence, the Mighty in prowess, the Self-Sufficient from the creatures, the Ample in pride, the Powerful over all that which You want, the Close in mercy, the Truthful in promise, the Opulent in favors, the Sympathetic in ordeals, the Nigh when Your are prayed, the All-encompassing of all that which You have created, the Accepter of the repentance of him who repents to You, the Powerful to do whatever You want, the Taker in all that which You decide, the Thankful for those who thank You, and the Rememberer of those who mention You. I pray You for I need You, I desire for You for I am in want of You, I resort to You for I am terrified, I weep before You for I am distressed, I seek Your aid for I am weak, and I depend upon You for I trust in none save You. (Please do) decide between our people and us with the truth, for they have deceived us, cheated us, disappointed us, betrayed us, and killed us. We are the progeny of Your Prophet and the sons of Your beloved one; namely, Muhammad the son of `Abdull¡h, whom You have chosen for the Divine Mission and for keeping Your Revelation. So, (please) prepare a way out and a relief for us, out of Your mercy, O most Merciful of all those who show mercy!
