Random Act of kindness : there were a few I was able to do,but they were not a secret,for instance I donated some money to an orphanage in my hometown. It was not a secret, the administrator gave receipts for it. Maybe the children didn’t know,but when someone knows it, in my mind it’s not a secret.
I put some gifts under the Christmas tree in the mall. This can be called a secret. I am not aware how it was received. I felt good, to me it counts.
We are supposed to give ‘zakat’ every year. I try to give money. Sometimes it’s not possible.
