The Book on Salutations and Greetings (Kitab As-Salam)
Muslim :: Book 26 : Hadith 5406
Abu Waqid al-Laith reported that Allah's Messenger (may peace be upon him) was sitting in the mosque along wish tome people when there came to him three persons; two of them stepped forward to the direction of Allah's Messenger (may peace be upon him), and one of them went away. The two stood by the side of Allah's Messenger (may peace be upon him), and one of them found a space in his circle and he sat in that; and the other one sat behind him and the third one went away. When Allah's Messenger (may peace be upon him) had finished his work, he said. Should I not inform you about these three persons? One of them sought refuge with Allah and Allah gave him refuge and the second one felt shy and Allah showed kindness to has shyness (and so he was accommodated in that meeting), and the last one reverted and Allah turned away His attention from him.
