I found these words at the end of this hadith in my father's book, in his own handwriting, joined to it, but he had crossed them out, so I do not know whether he recited them to me or not. They are, "The one who hears and obeys has no case against him, and the one who hears and disobeys has no case in his favor."
حدثنا
وجدت هذا الكلام في آخر هذا الحديث في كتاب أبي بخط يده متصلا به وقد خط عليه فلا أدري أقرأه علي أم لا وإن السامع المطيع لا حجة عليه وإن السامع العاصي لا حجة له
Its isnad is sahih, like the one before it, if the connection between the two hadiths is confirmed, for Abdullah has doubts, and his words suggest that he does not remember.
