O Son, it's raining in this city where I am temporarily stationed as a musafir for I know not how long I will be here.
That's the nature of our life, we walk and we stop under the shade of a tree and then we walk some more.
When it rains, I usually pray:
Allahumma soyyiban nafi'a.
O Allah, pour that which is beneficial.
And so must you.
When it rains, do say a prayer!
