There was a Campanion (Sahabi) to whom Prophet (ﷺ) said, by Allah I love you and I give some instruction to you. Never leave to recite this supplication after every (prescribed) Prayer, "Allahumma a inni ala dhikrika (zikrika), wa shukrika, wa ḥusni ibadatika", what is the name of that Campanion (Sahabi)?
