And (remember) when Musa (Moses) said to his boy-servant: "I will not give up (travelling) until I reach the junction of the two seas or (until) I spend years and years in travelling." 60 Then, when they reached their meeting, they forgot their fish, and it took its way into the sea, burrowing. 61 Moses asked his young companion when they crossed this point, "Bring us our food; the journey has made us tired." 62 He said, 'What thinkest thou? When we took refuge in the rock, then I forgot the fish-and it was Satan himself that made me forget it so that I should not remember it -- and so it took its way into the sea in a manner marvellous.' 63 'This is what we have been seeking' said he, and they retraced their footsteps 64 Then they found one from among Our servants whom We had granted mercy from Us and whom We had taught knowledge from Ourselves. 65 Moses said to him: "May l follow you that you may teach me something of the wisdom which you have been taught?" 66 'You will not bear patiently with me' He replied. 67 And how can you have patience in that of which you have not got a comprehensive knowledge? 68 He said: Allah willing, thou shalt find me patient and I shall not in aught gainsay thee. 69 He said: Well, if thou go with me, ask me not concerning aught till I myself make mention of it unto thee. 70
