Upon this the fisherman accepted his covenant that he would not hurt him, but that he would do him good; and when he had bound him by oaths and vows, and made him swear by the Most Great Name of God, he opened to him; and the smoke ascended until it had all come forth, and then collected together, and became, as before, an 'Efreet of hideous form. The 'Efreet then kicked the bottle into the sea. When the fisherman saw him do this, he made sure of destruction, and said, This is no sign of good:--but afterwards he fortified his heart, and said, O 'Efreet, God, whose name be exalted, hath said, Perform the covenant, for the covenant shall be inquired into:[II_32]--and thou has covenanted with me, and sworn that thou wilt not act treacherously towards me; therefore, if thou so act, God will recompense thee; for He is jealous; He respiteth, but suffereth not to escape; and remember that I said to thee as said the sage Doobán to King Yoonán, Spare me, and so may God spare thee. The 'Efreet laughed, and, walking on before him, said, O fisherman, follow me. The fisherman did so, not believing in his escape, until they had quitted the neighbourhood of the city, and ascended a mountain, and descended into a wide desert tract, in the midst of which was a lake of water. Here the 'Efreet stopped, and ordered the fisherman to cast his net and take some fish; and the fisherman, looking into the lake, saw in it fish of different colours, white and red and blue and yellow; at which he was astonished; and he cast his net, and drew it in, and found in it four fish, each fish of a different colour from the others, at the sight of which he rejoiced. The 'Efreet then said to him, Take them to the Sulṭán,[II_33] and present them to him, and he will give thee what will enrich thee; and for the sake of God accept my excuse, for, at present, I know no other way of rewarding thee, having been in the sea a thousand and eight hundred years, and not seen the surface of the earth until now: but take not fish from the lake more than once each day: and now I commend thee to the care of God.--Having thus said, he struck the earth with his feet, and it clove asunder, and swallowed him.
