A pious person رحمۃ اللہ تعالٰی علیہ saw Satan standing in worry by the Masjid door and asked, ‘What’s the matter with you?’ Satan replied, ‘Look inside.’ When the pious person looked inside he saw a person offering Salah and another person sleeping by the Masjid door. Satan said, ‘I want to enter the Masjid to distract the person offering Salah by putting evil thoughts in his heart, but the man that is sleeping by the door is a fasting person. When he breathes out, his breath prevents me from entering like a flame of fire.’ (Rau]-ul-Faiq, p. 39)
