٩ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنْ عَلِيِّ بْنِ النُّعْمَانِ عَنْ أَبِي أُسَامَةَ قَالَ سَمِعْتُ أَبَا عَبْدِ الله (عَلَيهِ السَّلام) يَقُولُ عَلَيْكَ بِتَقْوَى الله وَالْوَرَعِ وَالإجْتِهَادِ وَصِدْقِ الْحَدِيثِ وَأَدَاءِ الأمَانَةِ وَحُسْنِ الْخُلُقِ وَحُسْنِ الْجِوَارِ وَكُونُوا دُعَاةً إِلَى أَنْفُسِكُمْ بِغَيْرِ أَلْسِنَتِكُمْ وَكُونُوا زَيْناً وَلا تَكُونُوا شَيْناً وَعَلَيْكُمْ بِطُولِ الرُّكُوعِ وَالسُّجُودِ فَإِنَّ أَحَدَكُمْ إِذَا أَطَالَ الرُّكُوعَ وَالسُّجُودَ هَتَفَ إِبْلِيسُ مِنْ خَلْفِهِ وَقَالَ يَا وَيْلَهُ أَطَاعَ وَعَصَيْتُ وَسَجَدَ وَأَبَيْتُ.
9. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from Ali ibn al-Nu’man from abu ‘Usama who has said the following: “I heard Abu ‘Abdillah  saying, ‘You must be pious before Allah, restrain yourself against worldly matters, work hard, speak the truth, keep the trust, have good moral behaviors, be good to your neighbors and be so good that you can attract people without preaching to them by your tongues. Be an honor for us and not a disgrace. You must take a long time during your Ruku’ and Sajda (bowing down in prayer and prostration). When one of you takes a long time during his Ruku’ and Sajda, Satan cries behind him, “Woe upon me, he is obedient and I disobeyed. He prostrates (before the Lord) and I refused.””’
