Standing in the rain
It is Sunnah - A practice of the Prophet

to stand in the rain and to expose a portion of your body to it.
Its narrated by Imaam Muslim in his authentic compilation from the hadith of Anas, He said: It rained upon us as we were with the Messenger of Allah (may peace be upon him). The Messenger of Allah (may peace be upon him) unveiled his garment (from a part of his body) until the rain fell on him. We said: Messenger of Allah, why did you do this? He said: Because it (the rainfall) has just come from the Exalted Lord.
Scholars of jurisprudence have mention the following regarding standing in the rain:
1. The Sunnah of exposing oneself to the rain can be obtained by unveiling any portion of one’s body no matter how small the portion may be like one’s head or arms.
2. One should not expose one’s Awrah.
3. Avoid standing in the rain if it may cause harm or sickness to oneself.
4. It is recommended by some scholars to take Wudu (ablution) and Ghusl (wash) from the rainfall. And they based their deduction on the following Hadith: It is narrated from the Prophet (may peace be upon him) that when stream used to flow he (Prophet) would say: “Leave with us to that which Allah has made pure so that we may purify ourselves from it and praise Allah most exalted.”
Imaam Albayhaqee states that this is a narration from Umar (may Allah honour him) and not from the Prophet (may peace be upon him).
Imaam Nawawiy also mentions in Al-Majmoo’ that: “Its recommended that when the gorge flows (with rain water) to perform wudu (ablution) and ghusl (washing) from it. And if he or she is not able to do both then at least to perform wudu (ablution) from it.
And Allah knows best
