According to Traditions, Hazrat Imam Ali ع was born on the 13th of Rajab About 23 years before Hijrah, within the Blessed Precincts of the Holy Kaaba.
Sayyed Khwaja Moinuddin Hasan Chishti (Ajmeri) ر Mentions this Fact in His Famous Quartet:
Waqtiki Bakabah Murtaza Shood Paida;
Dar Ard U Sama Jalwa Numa Shood Paida
Jibra’eel Za Asm’an Faru Amad U Guft;
Ai Khatmi Rusul Farzand Ba Khanai Khuda Shood Paida.
What a time it was, when Ali ع was born in the Kaaba. Shimmering Light (Nur) was spread right from the Earth to the Sky.
Jibra’eel appeared and proclaimed: O Messenger (صلى الله عليه وآله وسلم)! What a blessing of Allah ﷻthat a son has been born inside the Kaaba
13th Rajab Narray Haideri Ya Ali عليه السلام .
اللَّهُمَّ صَلِّ عَلَى سَيِّدِنَا مُحَمَّدٍ وَعَلَى آلِ سَيِّدِنَا مُحَمَّد
