1405. Narrated Aboo Waaqid Al-Laithee (radhi Allaahu anhu) :

While  Allah’s Messenger (Sallallaahu Alaihi Wasallam) was sitting in the mosque with some people, three men came. Two of them came in front of Allaah’s  Messenger (Sallallaahu Alaihi Wasallam) and the third went away. The narrator added : The two persons kept on standing before Allaah’s  Messenger (Sallallaahu Alaihi Wasallam) for a while and then one of them found a place in the circle and sat there while the other sat behind them (the gathering,) and the third one went away. When Allaah’s  Messenger (Sallallaahu Alaihi Wasallam) finished his preaching, he said,

“Shall I tell you about these three persons? One of them betook himself to Allaah, so Allaah took him into His Grace and Mercy and accommodated him, the second felt shy from Allaah, so Allaah sheltered him in His Merccy (and did not punish him), while the third turned his face from Allaah and went away, so Allaah turned His Face from him (likewise).”
