The Kaaba, the oldest sacred house in the world, has a black stone. In Arabic it is called - Hajre Aswad. Everyone knows more or less an incident about Hazare Aswad. That is , after the rebuilding of the Ka'bah, there was a dispute among the Quraish as to who would replace Hazrat Aswad. Then the Prophet Muhammad (peace be upon him) took off the sheet of his body and left it in it and asked all the chiefs of the tribe to hold the sheet . It is the heavenly stone. In this connection it has been narrated in the hadith , narrated from Hazrat Ibn Abbas (RA) , Hazrat Rasoolullah (SAW) said , ' Hazrat Aswad has come down from Paradise. And its color was whiter than milk. In other words , it was whiter than ice. Later, the sin of Adam's son made him black. ' - Tirmizi Hajre Aswad is located in the south-east corner of the Holy Kaaba , at a height of 1.10 m above the ground . Hazre Aswad is 25 cm long and 16 cm wide. It is surrounded by a silver fence. You have to put your head inside the enclosure and kiss the stone. There was a piece of Aswad before. The Karamata community picked up the stone in 319 AH and took it to their area. At that time the stone broke into 6 pieces. The largest of these pieces is like a date. The pieces have now been replaced with another stone. Which is surrounded by a silver fence. So the stone with the silver border is not kissed but the pieces of Hazrat Aswad placed in it are considered to have been kissed or touched only if they can be kissed or touched. Hazare Aswad's side is guarded by Saudi police 24 hours a day. They make sure that no one is bothered to put their head in the enclosure or kiss. According to a hadith , ' Rukn (Hajre Aswad) and Maqam Ibrahim - two of the Yakut stones of Paradise. Which Allah has made lightless. If he had not dimmed it , it would have illuminated the east and the west. ' Narrated Tirmidhi Ibn Umar: The Prophet (peace and blessings of Allaah be upon him) said , " Surely the sins are forgiven by touching them (Hajar Aswad and Rukne Yamani)." - Narrated from Sunan Nasai Ibn Abbas (RA) , Hazrat Rasulullah (SAW) said about Hazrat Aswad , ' By Allah , Hazrat Aswad will be resurrected by Allah on the Day of Resurrection. He will have two eyes with which he will see , and one tongue with which he will speak. Whoever kisses or touches him will bear witness on the Day of Resurrection. ' -Ahmed One of the attractions of Holy Kaaba Sharif is Hazrat Aswad. By kissing this stone, the Muslims performing Hajj and Umrah attain endless peace. Hazare Aswad was kept under guard for 24 hours. The guards kept a close watch on Hazrat Aswad and the countless Muslims gathered around him. He also showed me how to kiss Hazare Aswad properly. It is also their responsibility to make those who want to kiss Hazare Aswad stand in line.
