And remember when We diverted some of the Sprites to you to hear the Reading. When they attended it, they said: “You keep silent!” Then, when it was completed, they returned to their people as warners.
When Messenger Muhammad realized that no one from his Quraishee tribe was ready to accept the Lord’s Message, he went to propagate Allah’s Message to Thwaef, the native place of his mother. Not only did they reject him and the Message, but they also chased him by stoning and insulting him with the help of goons and rowdies.
While returning from Thwaef, disappointed and exhausted, he spent the night at Sailul Kabeer in Nakhla valley. In the morning prayer, Allah sent some Spirits to make them hear the Reading from the Lord’s Book. Since there was none among humans to listen, Allah caused Sprites to hear the Message. On hearing It, they returned to their people as warners.
This means that if anyone among mankind reads Adhikr carefully by participation of the soul, he can transform his Jinn Soulmate (Sprite comrade) into a believer. See explanation 7:205-206; 16:43-44; 39:23; and 72:1-2.
