“Once, I asked abu Ja‘far (a.s.), about the case of a soldier who does not have Wudu’ and what is he required to do when he is not able to dismount? He (the Imam) said, ‘He can make Tayammum on his pad, saddle or mane of his stumper over which dust accumulates. He then performs Salah (prayer), makes Sujud (prostrations) lower than Ruku‘ (bowing down on one’s knees) and does not turn to al-Qiblah (al-Ka‘bah) but turns his face wherever his stumper goes, except that he turns to al-Qiblah (al-Ka‘bah) when saying the first Takbir (Allah is great beyond description) when paying attention.’”
