Nile and Euphrates rivers flow from heaven another error,

Narrated Abbas bin Malik: ...So when I went (over the seventh heaven), there I saw
Abraham. Gabriel said (to me), 'This is your father; pay your greetings to him.' So I greeted him and he returned the greetings to me and said, 'You are welcomed, O pious son and pious Prophet.' Then I was made to ascend to Sidrat- ul-Muntaha (i.e. the Lote Tree of the utmost boundary) Behold! Its fruits were like the jars of Hajr (i.e. a place near Medina) and its leaves were as big as the ears of elephants. Gabriel said, 'This is the Lote Tree of the utmost boundary) . Behold ! There ran four rivers, two were hidden and two were visible, I asked, 'What are these two kinds of rivers, O Gabriel?' He replied,' As for the hidden rivers, they are two rivers in Paradise and the visible rivers are the Nile and the Euphrates.'... Sahih Bukhari 5:58:227
