Uthamah bin Qays al-Bajali (may Allah be pleased with him) narrates from Sayyiduna Abdullah bin Sufyan al-Azdi (may Allah be pleased with him), and both of them were Companions of the Prophet (peace and blessings be upon him), that he said: "Whoever fasts one day in the path of Allah, Allah Almighty distances him from Hell by the distance of a hundred years."
Habib (may Allah have mercy on him) asked Abu Bishr (may Allah have mercy on him): "Two hundred years?" Abu Bishr (may Allah have mercy on him) said to Uthamah bin Qays (may Allah be pleased with him): "I too thought so." At this Sayyiduna Abdullah bin Sufyan (may Allah be pleased with him) said: "I am only telling you what I heard; I am not telling you what you are telling me."
No one narrated this hadith from Habib bin Ubayd (may Allah have mercy on him) except Hariz bin Uthman (may Allah have mercy on him), and it is not narrated from Sayyiduna Abdullah bin Sufyan al-Azdi (may Allah be pleased with him) except with this chain.
