Musannaf Ibn Abi Shaybah 36741 — Reports on the description

It is narrated from Ka'b that in Paradise there is a ruby with neither crack nor joint in it. In it there are seventy thousand houses, and in every house seventy thousand houris. Only a prophet, a truthful one, a martyr, a just ruler, or a person who passes judgement on his own self will enter it. The narrator said: We said: "O Ka'b! Who is the 'one who passes judgement on his own self'?" He said: "A person whom the enemy captures and then gives the choice either to adopt disbelief or to hold fast to Islam and be killed, and he chooses to hold fast to Islam."
