Is it true that the Prophet (peace be upon him) used to see behind him, and transform his saliva from salty water to fresh, and see in the dark?

The Prophet (peace and blessings be upon him) could see behind him, and this is confirmed among his miracles, as he said: "By Allah, neither your bowing nor your prostrating is hidden from me. Indeed, I see you from behind my back."

As for the transformation of salty water into fresh, it was narrated in a weak report from Hammam bin Nuqaid Al-Sa'di that the Prophet gave him water to pour into a salty well, and it became fresh. However, scholars have not mentioned this among his miracles.

As for his vision in the dark, it was narrated in reports that Aisha and Ibn Abbas said: "The Messenger of Allah (peace and blessings be upon him) used to see at night in the darkness, just as he would see during the day in the light." However, scholars and researchers have not mentioned this among his miracles, whereas they unanimously agreed on his ability to see from behind his back.
