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.
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.
