If you are capable of (waking up in) the morning and (ending) the evening, while there is nothing of deception in your heart for anything, then do so.' Then he said to me: 'O my son! That is from my Sunnah. Whoever revives my Sunnah then he has loved me. And whoever loved me, he shall be with me in Paradise.'"
