Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him) and Sayyiduna Imran bin Husayn (may Allah be pleased with him) narrate that the Prophet (peace and blessings be upon him) said: "Whoever takes a ritual bath (ghusl) on Friday, his sins and his faults are removed from him. When he sets out walking, twenty good deeds are recorded for him in return for every single step. When he finishes the prayer, he is rewarded with the deeds of two hundred years."
Imam al-Tabarani recorded this narration in al-Mu'jam al-Kabir and al-Mu'jam al-Awsat. Its chain contains a narrator, al-Dahhak bin Humrah, whom Yahya bin Ma'in and Imam al-Nasa'i (may Allah have mercy on him) declared da'if (weak). Ibn Hibban mentioned him in the book "al-Thiqat".
