أبي - رحمه الله - قال: حدثنا سعد بن عبد الله: عن أحمد بن محمد، عن أبيه، عمن ذكره، عن خيثمة بن عبد الرحمن الجعفي قال: سأل عيسى بن عبد الله القمي أبا عبد الله عليه السلام وأنا حاضر فقال: ما العبادة؟ قال: حسن النية بالطاعة من الوجه الذي يطاع الله منه.
1.	My father, may Allah grant him mercy, said: We were told by Sa’d bin Abdullah, from Ahmad bin Muhammed, from his father, from the one he mentioned, from Khaithama bin Abdul-Rahman al-Ju’fi, that he said: Isa bin Abdullah al-Qommi asked Abu Abdillah, peace be upon him, while I was present. He said: What is worship? He said: A good intention of obedience from the aspect from which Allah is obeyed.
