Mukhtasar Muslim (Abridged) 448 — Blessing of rain

Sayyiduna Anas (may Allah be pleased with him) says: We were with the Messenger of Allah (peace and blessings be upon him) when it rained upon us, so the Messenger of Allah (peace and blessings be upon him) removed his garment until the rainwater reached him. We said: O Messenger of Allah (peace and blessings be upon him)! Why did you do this? He (peace and blessings be upon him) said: Because it has just now come from its Lord.
