Muawiya Qushayri reported,

I said, "Prophet of Allah, I did not come to you until I had sworn more times than the number of these fingers of his hands that I would never come to you nor follow your religion. I was a man who understood nothing except what Allah and His Messenger taught me. I ask you by the revelation of Allah, with what did your Lord send you to us?"He replied, "With Islam."I asked, "And what are the signs of Islam?"He said, "That you say, 'I have submitted my face to Allah and devoted myself to Him,' that you establish the prayer, and that you give the zakat."

عن بهز بن حكيم يحدث عن أبيه عن جده قال

قلت يا نبي الله ما أتيتك حتى حلفت أكثر من عددهن لأصابع يديه أن لا آتيك ولا آتي دينك، وإني كنت امرأ لا أعقل شيئا إلا ما علمني الله عز وجل ورسوله، وإني أسألك بوحي الله بما بعثك ربك إلينا؟ قال: بالإسلام. قلت: وما آيات الإسلام؟ قال: أن تقول أسلمت وجهيي إلى الله، وتخليت ونقيم الصلاة، وتؤتي الزكاة.
