These two narrations differ in wording, though the narrator (Abu Hammam) is the same. In one narration, Abu Hammam reports from Imam al-Ridha عليه السلام, as recorded by Muhammad ibn Ali ibn Mahbub, while in the other narration, recorded by Muhammad ibn Ahmad ibn Yahya, it is attributed to Muhammad ibn Sa‘id ibn Ghazwan. This variation weakens the reliability of the report. If the narration were authentic, it could be interpreted as recommending tayammum for each prayer out of desirability, akin to the recommendation for renewing wudu, even though performing multiple prayers with a single wudu is permissible by consensus. Another possibility is that the statement refers to a situation where water becomes available between prayers, in which case tayammum would no longer suffice, and wudu would become obligatory. Moreover, Abu Hammam has also narrated reports that contradict this narration and align with the interpretation that multiple prayers can be performed with one tayammum, supporting the position we have adopted.
