Is the meaning of the phrase "with every prayer" in the noble Prophetic Hadith using the siwak when standing in the row for prayer, or during ablution, or before the prayer is established, or while going to the mosque?

The four schools of thought (madhhabs) agree that using the miswak (tooth-stick) is a sunnah (prophetic tradition) when performing ablution (wudu'). However, they differ on whether it is one of the sunnahs of ablution itself. The Hanafis, Malikis, and one opinion among the Shafi'is hold that it is a sunnah of ablution. In contrast, the Hanbalis and the more prominent opinion among the Shafi'is believe it is a sunnah external to ablution, preceding it.

As for using the miswak for prayer (salat), there are three schools of thought: 1. An opinion among the Shafi'is emphasizes using the miswak for every prayer, whether obligatory (fard) or supererogatory (nafl). If one forgets it, it is sunnah to make it up. 2. An opinion among the Hanafis states that it is sunnah for ablution, not for prayer, but their relied-upon position is that it is prescribed for both. 3. The Maliki position recommends using the miswak for an obligatory or supererogatory prayer if a considerable time has passed since the previous use of the miswak, according to custom.

The exact time for using the miswak for prayer is not clearly specified; rather, it is done when prayer is approaching, according to custom.
