Blowing on water after performing ruqyah

Question: Is it permissible to blow on water after performing ruqyah? Please clarify the issue according to the Quran and Sunnah.
Answer: The Prophet Muhammad (peace be upon him) forbade blowing on drinking substances.
It is narrated from Sayyiduna Abu Saeed Khudri (may Allah be pleased with him):

ان النبي صلى الله عليه وسلم نهى عن النفخ في الشرب فقال رجل : القذاة اراها في الإناء قال : اهرقها

“The Prophet (peace be upon him) forbade blowing into drinking things. A man said: ‘What if I see a straw in the vessel?’ He (peace be upon him) said: ‘Then pour out that water.'”
