Almost half of gurkhana is occupied by magnificent stepped ceramic gravestone, which was installed at the time of Amir Temur, in the 1380s. Ibn Battuta witnessed that, earlier, there was encrusted ebony gravestone, coated by silver at the corners, with three lamps alight. The traces of any deposition have not been revealed under the gravestone. Nearby the eastern edge of the gravestone there is a male deposition in the ground-grave of the 11th century. The gravestone of Kusam ibn Abbas has a form of five-stepped pyramid faced with majolica tiles. Floral ornament alternates with Arabic lines from Koran and hadiths. The upper step has a vaulted form of "sagana". At the flat ends of the upper step there is an inscription: “This is a tomb of the son of the uncle, lord of messengers, seal of prophets and messenger of the god; regards to him, emir of true Muslims, Kusam, the son of al-Abbas, so be Allah pleased with both of them, and give them to eat and to drink. He died in year fifty seventh (676/677H)”. The third step bears lines from Koran: “Anyhow do not consider dead those, which were killed on a way of Allah. No, they are alive!” Hence another hypothesis about the name of the complex - "Shahid-Zinda" – “Alive martyr of faith”. At the fourth step, there is an inscription: “This is the highest of palaces – paradise, illuminating hearts, spreading the light and involving the devout. For them [are] gardens where the rivers are running down”. This is the tomb of Kusam, the son of Abbas, inspired by the talk with the lord of leaders and gifted, the prophet of people and airy spirits, the messenger of Allah and teacher of humanity. So be Allah pleased with him and grant him the peace”.
