Sahih Adab al-Mufrad

It is narrated from Sayyiduna Abdullah bin Abi Awfa, who narrates from the Prophet (peace and blessings be upon him) that he (peace and blessings be upon him) used to supplicate: «اللهم لك الحمد ملء السماوات وملء الأرض، وملء ما شئت من شيء بعد، اللهم طهرني بالبرد والثلج والماء البارد، اللهم طهرني من الذنوب ونقني كما يُنقى الثوب الأبيض من الدنس» "O Allah! All praise is for You, as much as fills the earth, as much as fills the heavens, and as much as You will after that. O Allah! Purify me with hail, snow, and cold water. O Allah! Cleanse me from sins and purify me as a white garment is cleansed from dirt."
