A devotee was praying when Satan appeared to him and said: “How long wilt thou cry ‘O Allâh?’ Be quiet for thou wilt get no answer.” The devotee hung his head in silence. After a while he had a vision of the prophet Khidr, who said to him, “Ah, why hast thou ceased to call on God?” “Because the answer, ‘Here I am,’ came not,” he replied. Khidr said, “God hath ordered me to go to thee and say this: ‘Was it not I that summoned thee to My service? Did I not make thee busy with My name? Thy calling “Allâh!” was My “Here I am,” Thy yearning pain My messenger to thee. Of all those tears and cries and supplications I was the magnet, and I gave them wings’”.
