Bandeja de Entrada - MillanMillan

Hi
I was sent a message to translate this sentence..
(Yesterday is history, tomorrow is a mystery and today is a gift) but was denied that when I tried .. I am sending it to you
تمتع باليوم فالامس قد مضى والغد ما زال يكتنفه الغموض

Can you please give me your feadback
