The same applies to the foot: if part of it has been amputated, he washes what remains; and if it has been amputated at the ankle joint, he washes the end of the lower leg adjacent to it, because it is part of it.
Likewise, with regard to the ear: if part of it has been cut off, he wipes what remains. If all of it has been cut off, wiping its outer surface is no longer required, though he inserts his fingers into the ear canals.
He then raises his gaze to the sky …
His statement, “He then raises his gaze to the sky,” is a sunnah if the hadith is authentic. This is based on what has been narrated—that the Prophet, peace and blessings be upon him, said: “Whoever performs ablution and performs it well, then raises his gaze to the sky and says: ‘I bear witness that there is no god worthy of worship but Allah, alone, with no partner; and I bear witness that Muhammad is His servant and Messenger,’ the eight gates of Paradise will be opened for him, and he may enter through whichever of them he wishes.” (1)
However, its chain of transmission contains an unknown narrator. The status of an unknown narrator is not known: whether he is precise in narration, trustworthy, or otherwise. If a chain of transmission contains an unknown narrator, the hadith is judged to be weak.
The jurists, may Allah have mercy on them, based this ruling on this hadith and on the rationale that he raises his gaze to the sky as an indication of Allah Most High’s exaltedness, since he has borne witness to His oneness.
