Abu Khizamah narrated from his father who said:
"I asked the Messenger of Allah (S.A.W): 'O Messenger of Allah(S.A.W)! Do you think that the Ruqyah we use, the treatments we use, and what we seek to protect ourselves will contradict anything from Allah's Decree?' He said: 'They are from Allah's Decree.'"
