The last Tahirian emir and the extinction of this dynasty by Yaqub Leith/Mohammed Tahir Abdullah, the last Taherian emir, he was a fun-loving and lustful man and spent most of his time drinking and reveling.. During his time, the Alawites revolted in Tabaristan and expelled the Tahiri ruler from there. At the same time, Yaqub Leith came to power in Sistan and took advantage of the opportunity and attacked Khorasan by inviting Tahir's relatives and cousins.. Beyhaqi writes: The nobles and nobles and government of Taheri wrote a letter to Yaqub asking him to come as soon as possible because there is nothing to do with Muhammad Taher except for fun and entertainment.. When Muhammad Tahir saw the attack approaching, he sent a representative to Yaqub and gave him the following message: if you have come under the order of the Caliph, submit his order so that I will hand over the governorship to you, otherwise you will return.:This is my command. Yaqoob conquered Khorasan in the year 259 of the lunar calendar and arrested Muhammad bin Tahir and his family and seized all his property.. and sent him handcuffed to Bam Castle in Kerman.
