It is narrated from Sayyiduna Abu Qatadah (may Allah be pleased with him) that when we were returning from the expedition of Tabuk (then he narrated the whole hadith);
and in this narration it is also mentioned that he (peace and blessings be upon him) said: "Whoever among you meets any of those who stayed behind (from the expedition without excuse), let him neither speak to them nor sit in their company."
And in it these words are also reported, that he (peace and blessings be upon him) said: "This is Taybah (Madinah). My Lord has settled me here. This city expels the filth and impurity of its inhabitants just as the blacksmith's bellows removes the rust and dross of iron. So whoever among you meets any of those who stayed behind, let him neither speak to them nor sit with them."
