It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that he said: I heard Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him) saying that the Messenger of Allah (peace and blessings be upon him) said: "Whoever performs the ritual bath (ghusl) on Friday, his sins and errors are forgiven; then when he begins walking to the Friday prayer, for every step he receives the reward of twenty years of deeds; and when he finishes the Friday prayer, he is granted the reward of two hundred years of deeds."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Sayyiduna Abu Bakr (may Allah be pleased with him) only with this chain; Yahya bin Sulayman is alone in narrating it."
It is like this in the Dar al-Haramayn printed edition, and the correct word is probably "al-Hafari".
