The following is a whatsapp post in a group I am in.
*Ketua Hospital Kerajaan Dr. Adib Rizvi, pakar buah pingang memohon agar semua Muslim menahan diri dari minum sebarang air gas. Terutama air gas yg sejuk dalam bulan Ramadan akan datang ini. Kata beliau setelah berpuasa sepanjang hari buah pinggang akan kekeringan, buah pinggang akan berhenti dengan meminum air sejuk ini. Semua minuman sejuk seperti 100plus, Coke, Pepsi, Fanta, Miranda, 7up, Sprite, Mountain Dew dan lain lain hendaklah dielakkan sepenuhnya. Adalah lebih baik minum jus buah buahan segar tanpa ais.*
*Sebelum bulan ramadan tiba, tolong sebarkan makluman ini kepada semua Muslim yang anda kenal, agar kita sihat untuk bribadat.*
A quick google seaech on dr adib rizvi showed that the person cited denied he ever posted nor stated such things.

Now I am not promoting drinking of softdrinks, as I personally have reduced drinking high carbohydrate foods and drinks when I can. But this info is just ridiculous stating the kidneys will stop functioning when you drink soft drinks. If it did you would ve dead in a few weeks.
It will however happen if you were dehydrated, soft drink whether hot or cold is better than being dehydrated.

Looking into it further though, some cola drinks have been found to cause kidney stones.
consumption of 2 or more cola beverages per day was associated with an increased risk of chronic kidney disease. We saw no increase in risk associated with consumption of noncola carbonated beverages, or with noncola caffeinated beverages.
Mostly attributed to the phosphoric acid in the drinks.
