Tafsir of Ash-Shu`ara' 26:79

And it is He Who feeds me and gives me to drink. He is my Creator Who provides for me from that which He has made available in the heavens and on earth. He drives the clouds and causes water to fall with which He revives the earth and brings forth its fruits as provision for mankind. He sends down the water fresh and sweet so that many of those whom He has created, animals and men alike, may drink from it

وإذا مرضت فهو يشفين
