Regarding this narration, the following points are notable: 1. It is a mursal (interrupted) and disconnected narration because, in the first transmission, Ja‘far ibn Bashir states, “from the one who narrated it,” which is an unknown source, rendering the narration unreliable and subject to dismissal. 2. In the second transmission, Ja‘far ibn Bashir mentions, “from ‘Abdullah ibn Sinan or someone else,” showing uncertainty in the chain of narration, which further weakens its reliability. For narrations of this nature, which contain ambiguity or interruption in the chain, they are not considered binding evidence. However, if the narration were deemed reliable despite its weaknesses, it would be interpreted to apply to someone who deliberately caused themselves to be in a state of janabah and subsequently feared for their life due to cold conditions. In such cases, they would perform tayammum, offer their prayer, and then repeat it later when the conditions are favorable. However, the better course of action for them would still be to perform ghusl if possible, as will be elaborated upon later. Evidence further supports that someone who performs tayammum due to janabah and prays is not obligated to repeat the prayer.
