1 - قال: أخبرني أبو حفص عمر بن محمد الصيرفي قال: حدثنا أبو الحسن علي ابن مهرويه القزويني سنة اثنتين وثلاثمائة قال: حدثنا داود بن سليمان الغازي قال: حدثنا علي بن موسى عليهما السلام، عن أبيه العبد الصالح موسى بن جعفر، عن أبيه الصادق جعفر بن محمد، عن أبيه الباقر محمد بن علي، عن أبيه زين العابدين علي ابن الحسين، عن أبيه الشهيد الحسين بن علي، عن أبيه أمير المؤمنين علي بن أبي طالب عليهم السلام قال: قال رسول الله صلى الله عليه وآله وسلم: أفضل الأعمال عند الله إيمان لا شك فيه، وغزو لا غلول فيه، وحج مبرور. وأول من يدخل الجنة عبد مملوك أحسن عبادة ربه ، ونصح لسيده، ورجل عفيف متعفف ذو عبادة.

1. He said: Abu Hafs Umar ibn Muhammad al-Sayrafi reported to me from Abul Hasan ‘Ali ibn Mahrawayh al-Qazwini, in the year 302, reporting from Dawood ibn Suleiman al-Ghazi, that ‘Ali ibn Musa, peace be upon him, reported from his saintly father Musa ibn Ja’far, from his father al-Sadiq Ja’far ibn Muhammad, from his father al-Baqir Muhammad ibn ‘Ali, from his father Zainul Abideen ‘Ali ibn al-Husayn, from his father al-Shaheed Al-Husayn ibn ‘Ali, from his father Amirul Mu’mineen ‘Ali ibn Abi Talib, peace be upon them all, that: The Prophet, peace be upon him and his progeny, said: "The best act in the estimation of Allah, is to have faith unblemished by any doubt, and to fight in His way, without being dishonest about the spoils, and to perform Hajj, which is accepted into the grace of Allah. And the slave who worships Allah in the best manner, remains sincere to his master and the one who is chaste, incorruptible and worshipful, will be the first to enter Paradise."
