Before anything, lets send Durood upon our Holy Prophet (PBUH)
Allah-humma Sall-e-Alaa Muhammad, Wa Alaa Aali Muhammad, Wa Baarik Wa Sallim
Here are some narrations regarding the events that took place at the time ofbirth of the most dignified Messenger of Allah Muhammad Al-Mustafa (peace be upon him and his pure progeny) known as Sadiq (the Truthful) and Amin (the Trusted) and was sent as "The Mercy for this World and the Hereafter":
Aminah (Peace be upon her), the mother of the Prophet (Peace be upon him and his pure progeny), said that at the time of his birth she heard many voices having no human resemblance, and saw displayed a banner of the silk of paradise, mounted on a staff of ruby and filling all the space between heaven and earth. Light beamed from the head of the child, illuminating the heavens.
It is related on the authority of Imam Ja`far As-Sadiq (Peace be upon him) that Iblees was at first allowed to go up even to the seventh heaven and listen to the reports of those blessed abodes, but when Prophet Isa (peace be upon him) was born, Iblees was inhibited to the three heavens, and on the birth of Muhammad (peace be upon him and his pure progeny) the demons were debarred from them all, and driven by arrows of meteoric fire from the gates of those celestial regions.
At the birth of the Prophet,
1) Every idol fell on its face
2) The palaces of Kesry, emperor of Persia, trembled, and fourteen of the towers fell
3) Lake Sivah that was worshipped disappeared (ts site is the salt plain near Kasham)
4) The Valley of Samavah, where for a number of years no water had been seen, now flowed with that element
5) The sacred fire of Fars, which had not been extinguished for a thousand years, were quenched that night.
6) The wisest of the clerics dreamed that a number of strong camels led the horses of Arabia across the Tigris into their territory.
7) On that night a light appeared in Hijaz (A district of Arabia, including Makkah) filling the whole world and moving eastward.
8) The following morning, the thrones of all the kings were found reversed; the skill of the soothsayers (fortune-teller) departed, the magic of the sorcerers ended.
At the birth of the Holy Prophet Muhammad (Peace be upon him and his pure progeny) Iblees shrieked among his infernal children who drew to inquire what new curse had befallen him. Woe to you! he cried, throughout this night I have observed momentous changes in the heavens and the earth. Some great event must have transpired on earth unparallel since the ascension of Isa to heaven; fly to discover what it is. The subordinate fiends (beasts) flew in all directions, on their infernal errand (task), but returned without making any discovery to satisfy the doubts of Iblees, who then undertook the matter himself, glided down to the earth, and sought far and wide around, till at last, coming to Makkah, he found the sacred place encircled by a host of angels, who repelled him with a shout. He then assumed the form of a sparrow and entered the city, but angel Gabriel (peace be upon him) detected him in this disguise, and sternly said, Begone, accursed! He replied allow me only to ask what has occurred on earth the past night. Angel Gabriel (peace be upon him) answered: Muhammad (peace be upon him and his pure progeny), the best of the prophets, is born. Have I any portion in him? inquired the accursed. No, said Angel Gabriel (peace be upon him). But have I no portion in his sect? added the evil spirit. Yes, replied the archangel, upon which Iblees professed himself satisfied, and departed.
It is related from Ali (Peace be upon him), the commander of the faithful, that the idols which were in the Kaaba fell on their faces when the Prophet (Peace Be upon him) was born, and a voice proclaimed from heaven: "Truth is revealed and error is annihilated." The whole world was illuminating on that night, and every stone and clod and tree laughed for joy, and all things in heaven and earth uttered praise to Allah. Iblees fled, crying: The best and the dearest of creatures is Muhammad (Peace be upon him and his pure progeny)
Iblees, after learning what had transpired, assembled his offspring and cast dust on his head, crying: Since my creation no calamity like this has befallen me; a son is born whom they call Muhammad bin Abdullah (peace be upon him and his pure progeny); He will destroy idolatry, and require men to worship Allah in unity of His being. Hereupon the whole evil crew cast the dust of degradation on their heads, and fled to the fourth sea, where they wept forty days.
