SHAFAQNA – In a letter to his eldest son, Imam Hassan (AS), Imam Ali (AS) wrote: Entrust all your affairs with Allah (SWT), where you have reached a secure and powerful shelter. Call upon your God sincerely at the time of saying a prayer (Dua), as the Almighty has the power to forgive or to deprive. And request a lot from Allah (SWT) for goodness and blessing [1].
