By pairing the Healing the Sick Hadith accounts with your previous entry on water flowing from hands, you create an unshakeable case demonstrating a systematic, retroactive pattern of copying biblical miracles.
These stories claim Muhammad healed various physical ailments, often through his saliva and touch.
Sahih al-Bukhari 3009: During the Battle of Khaybar, Ali ibn Abi Talib was suffering from an eye infection. Muhammad "spat in his eyes and invoked Allah to cure him," and Ali was healed instantly.
Sahih al-Bukhari 4206: Muhammad is said to have healed the leg of Salama bin al-Akwa after it was wounded in battle by blowing his breath on it.
Surah 29:50-51 asks, "Is it not enough for them that We have sent down to you the Book?" This implies that the Quran was the only sign provided. If Muhammad could heal the blind or the lame, the Quran's persistent refusal to offer "signs" to skeptics becomes difficult to explain.
Muslim pologists will try to escape Surah 29:50-51 by claiming, "These healings weren't public signs (Ayat) meant to convince the pagan skeptics; they were private blessings (Barakah) meant only for the believers!"
This defense falls apart on impact. A public, instantaneous cure of a severe infection (like Ali's eyes) during a massive military campaign like Khaybar cannot be kept secret. If Muhammad possessed the inherent spiritual power to override biological laws at will, it would be a massive, undeniable Aya (sign). The Quran explicitly says Allah withheld such signs (Surah 17:59).
These accounts mirror the healing miracles of Jesus. Specifically, the use of saliva to heal eyes is found in Mark 8:23 and John 9:6. The Hadith writers likely attributed these acts to Muhammad to ensure he was not seen as "lesser" than Jesus in supernatural power.
While the Hadith writers copied the physical action but completely missed the theology behind it. When Jesus used saliva or mud, He was deliberately evoking Genesis 2—He was using the clay of the earth to recreate missing biological matter, demonstrating His identity as the Creator who originally formed man from the dust. Muhammad spitting into Ali's eyes is a hollow, magical imitation designed solely to check a box: "Look, our prophet can do the saliva miracle too!"
