The interpretation of this Hadith, which mentions wiping from the elbow to the fingertips once on the back and once on the front, aligns with the earlier explanation of Sama'ah's narration reported by Uthman ibn Isa. It indicates that the intent was the ruling, not the physical act. It is as if he said that by wiping the back of the hand, he attained the ruling of washing the hand from the elbow - both its front and back. This does not contradict our position. If someone claims that the earlier narrations - one from Abu Basir Layth al-Muradi from Abu Abdullah عليه السلام and another from Isma'il ibn Hammam al-Kindi from Imam al-Ridha عليه السلام, along with the narration of Safwan ibn Yahya from al-Ala from Muhammad ibn Muslim from one of the Imams عليه السلام - do not explicitly state that the two strikes or repetitions are exclusive to Ghusl for Janabah and not for Wudu', and argues that the obligation in Wudu' should also be two strikes, the response is: Numerous narrations establish that the obligation in Tayammum is once. When additional narrations specify two strikes, we interpret those relating to the ruling of once as applicable to Wudu' and those specifying twice as applicable to Ghusl for Janabah, so as to avoid contradictions between narrations. Moreover, we have already presented two narrations explaining these reports: one from Hariz, from Zurara, from Abu Ja'far عليه السلام, and another from Ibn Abi Umayr, from Ibn Udhaynah, from Muhammad ibn Muslim, from Abu Abdullah عليه السلام. These clarify that Tayammum for Wudu' is once and for Janabah is twice. Additionally, narrations, such as the one from Ibn Bukayr, from Zurara, establish that the obligation is once in general terms.
