Sayyiduna Sa’d bin Abi Waqqas (may Allah be pleased with him) says: We were with the Messenger of Allah (peace and blessings be upon him) when he said:“Is any one of you incapable of doing a thousand good deeds every day?”One of those sitting with him said:“How can any one of us do a thousand good deeds?”He (peace and blessings be upon him) said:“If he says ‘Subhan Allah’ one hundred times, a thousand good deeds will be written for him and a thousand sins will be erased from him.”
