Musannaf Ibn Abi Shaybah

Hazrat Alqamah narrates that I was coming from the place of Sileheen with Hazrat Abdullah bin Masood (may Allah be pleased with him), when some traders from the place of Heerah also joined him. When these people entered Kufa, they left that path and took another route. He turned towards them and saw that they had deviated from the path, so he greeted them with salam. I asked: Did you greet these disbelievers with salam? He replied: Indeed, these people chose to accompany me, and a companion also has some rights.
