Qays bin Saad reported,

His father brought him to the Prophet ﷺ to serve him. He said, "The Prophet ﷺ passed by me after I had prayed and nudged me with his foot, saying, 'Shall I guide you to one of the gates of Paradise?'I replied, 'Yes, please.'He said, 'There is no power and no strength except with Allah.'"In another wording, "A treasure from the treasures of Paradise."

عن قيس بن سعد بن عبادة

أن أباه دفعه إلى النبي ﷺ يخدمه قال: فمر بي النبي ﷺ وقد صليت فضربني برجله وقال: ألا أدلك على باب من أبواب الجنة؟ قلت: بلى قال: لا حول ولا قوة إلا بالله. وفي لفظ: كنز من كنوز الجنة.
