`Ubada b. as-Samit reported God's messenger as saying, "In paradise there are a hundred stages between each two of which there is a distance like that between heaven and earth. Al-Firdaus from which issue the four rivers of paradise is the highest of them, and above it is the Throne; so, when you make request from God ask Him for al-Firdaus." Tirmidhi transmitted it. I have not found it in the two Sahihs or al-Humaidi's book[*]. *In Masabih as-sunna the source of each individual tradition is not given but those in section 1 are all called sahih and come from Bukhari or Muslim, or from both. One therefore does not expect to find a tradition from Tirmidhi in section 1. It occurs in his collection in Sifat al janna, 4. In Masabih as-sunna it does not say that this tradition comes from 'Ubada, but the Mishkat is correct in attributing it to him. There is one like it from Abu Huraira in Bukhari, jihad, 4, but the wording is not identical.
