People of other tribes came to him and said...
People of other tribes came to him and said, You are going towards citizens who have been fooling others since a very long time. They have named their city ‘Haram’ and have built a house there and regard it as their Allah. They meant Makkah and the Ka‘bah. Tuba said, If what you say is correct then I would kill their men folk, imprison their boys and destroy their houses. At once, his eyes bulged out and hug over his face. Then Ulama and the progeny of Prophets were called.
He asked them to think and let him know why this trouble overtook him. They asked him: First of all tell us what was in your mind (intention). He replied, “I had intended that when I enter Makkah I will kill their men folk, capture their children and break their house (Ka‘bah).” They at once told him that in their opinion the only reason for his trouble was this intention entertained by him. He asked the reason.
They said that city is the Haram (sanctuary) of Allah and that house if the House of Allah and the residents of that city are the progeny of Prophet Ibrahim. Tubba said, You are right. Now tell me what I should do by way of repentance so that this trouble may be warded off. They said, Now decide and intend to do what opposite of your earlier is thought so that perhaps the trouble may be removed.
What they intended to convey was that he should now pay respect to Makkah and Ka‘bah and think of doing good to the residents of Makkah. With this new intention, his eyes went back to their original place. He then called that group which had inspired him to destroy Ka‘bah and killed them all. When he reached Makkah he covered Ka‘bah with a gilaaf and gave a feast to the citizens of the holy city for 30 days.
Every day 100 camels were sacrificed and its meat was put in big vessels placed in mountains for feeding the forest animals. Grass and grain was provided for four footed animals in fields and deserts. Then he came from Makkah to Medina and made some Yemenis reside there who belonged to the tribe of Bani Ghassaan so that they might await the arrival of the Prophet of the last age. Ansar are their progeny.
It is mentioned in another narration that he cut off royal dresses to make a cover for Ka‘bah and poured perfume on it. According to another tradition when Tubba bin hasan came to Medina he executed 350 Jews and wanted to destroy Medina. At that time a Jew who was 250 years old said, O King! Nobody is more oppressive than you.
