The birth of Imam Ali bin Abi Talib (as) took place under unique circumstances inside the Holy Kaaba at Makkah on the 13th of Rajab 600AD. It is considered unique because no prophet or saint has ever been born in a Holy sanctuary. Fatima bint Asad, the expectant mother of Imam Ali bin Abi Taleb (as) was praying outside the Holy Kaaba when she suddenly felt the labour pains and prayed to Allah (SWT) saying “O Allah! I believe in You and in the messengers and the scriptures You have sent. I believe in what has been said by my grandfather, Prophet Abraham (Ibrahim) who built the ancient house (Holy Kaaba). So, for the sake of the builder of this House, and for the sake of the child in my womb, I implore You to make my labour easy.” Just then the wall of the Holy sanctuary opened miraculously. As she stepped in, the wall closed behind her. Shortly after that she gave birth to her baby.
