It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "When you hasten towards good, walk barefoot, for Allah Almighty multiplies the reward (of the one who walks barefoot) many times over that of the one who walks wearing sandals."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith was narrated from Sufyan only by Sulayman; Yusuf is alone in narrating it."
