“There was a companion of ours in Glasgow who became ill and was hospitalized. He was admitted for three days and on the fourth day the attendant nurse said, “Marry me”.He [the brother in Glasgow] asked, “Why? I am a Muslim, you and I cannot become companions.”She said, “I will become Muslim”.”What’s the reason?” it was asked.She said, “In all my time that I have served in hospitals, except you, I have never seen a man lower his gaze in front of a woman. In my life you are the first person who lowers his gaze when seeing a woman. I come, and you close your eyes. Such great modesty can be taught by none other than a true religion.”The protection of one’s gaze entered Islam in her. She testified to the Oneness of Allah and became a Muslim. They both got married. By now, the same woman was and is the means of bringing so many other girls and women into Islam.
In a Hadith, the Prophet Muhammad (saw) is reported as having said: “And the eyes commit zina (adultery). Their zina is gazing.”The Prophet Muhammad (saw) commanded Imam Ali (as) said: “Ali! Do not look once after another, for the first look is for you (since it happens accidentally) while the second is against you.”
