Ubaadah bin Saamit reports that Rasulullah صلى الله عليه وسلم said one day when Ramadhaan had drawn near; “The month of Ramadhan, the month of blessings has come to you, wherein Allah turns towards you and sends down to you His special Mercy, forgives your faults, accepts prayers, appreciates your competition for the greatest, good and boasts to the angels about you. So, show to Allah your righteousness; for verily, the most pitiable and unfortunate one is he who is deprived of Allah’s Mercy in this month.”
