Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates: Sayyiduna Salman al-Farisi (may Allah be pleased with him) came to Sayyiduna Umar (may Allah be pleased with him), who was sitting reclining on a cushion. Sayyiduna Salman (may Allah be pleased with him) said: He pushed it towards me, then said: "O Salman, any Muslim whose Muslim brother comes to him, and he places a cushion for him out of honour for him, Allah Almighty will forgive that person."
Imam al-Tabarani recorded it. Its chain contains a narrator, Imran bin Khalid al-Khuza'i, and he is da'if (weak).
