Musannaf Ibn Abi Shaybah

Hazrat Rabee’ bin Zaid (may Allah be pleased with him) says that once the Messenger of Allah (peace and blessings be upon him) was walking when a boy from the Quraysh was walking a little off the path. Upon seeing him, the Prophet inquired about him, “Is this not such-and-such boy?” The people said, “Yes, it is him.” The Prophet called him and asked, “Why are you walking off the path?” He replied, “I want to avoid the dust.” The Prophet said, “Do not walk off the path, for by the One in whose hand is the life of Muhammad (peace and blessings be upon him), this dust is the fragrance of Paradise.”
