Hadith #2

3 - حدثنا محمد بن موسى بن المتوكل (رحمه الله)، قال: حدثنا علي بن الحسين السعد آبادي، قال: حدثنا أحمد بن محمد بن خالد، عن أحمد بن محمد بن أبي نصر البزنطي، عن حماد بن عثمان، عن عبد الله بن أبي يعفور، عن الصادق جعفر بن محمد (عليهما السلام)، قال: خطب رسول الله (صلى الله عليه وآله) الناس في حجة الوداع بمنى في مسجد الخيف، فحمد الله وأثنى عليه، ثم قال: نضر الله عبدا سمع مقالتي فوعاها، ثم بلغها من لم يسمعها، فرب حامل فقه غير فقيه، ورب حامل فقه إلى من هو أفقه منه ثلاث لا يغل (1) عليهن قلب امرء مسلم: اخلاص العمل لله والنصيحة لائمة المسلمين، واللزوم لجماعتهم، فإن دعوتهم محيطة من ورائهم المسلمون إخوة تتكافا دماؤهم، يسعى بذمتهم أدناهم، هم يد على من سواهم (2).

Muhammad b. Musa b. al-Mutawakkil (rh) narrated to us. He said: `Ali b. al-Husayn al-Sa`d Abadi narrated to us. He said: Ahmad b. Muhammad b. Khalid narrated to us from Ahmad b. Muhammad b. Abi Nasr al-Bazanti from Hammad b. `Uthman from `Abdullah b. Abi Ya`fur from al-Sadiq Ja`far b. Muhammad (as). He said: The Messenger of Allah (s) delivered a sermon to the people in his Farewell Pilgrimage in Mina in the Mosque of Khayf. So, he praised Allah and commended Him. Then, he said: May Allah grant joy to a servant who heard my sayings and understood them, then delivers them to those who did not hear them. There can be a carrier of knowledge who is not a person of understanding, and there could be a carrier of knowledge who brings it to one who is more knowledgeable than him. There are three things that the heart of a Muslim person does not feel trouble in: (1) sincerity in deeds for Allah, (2) wishing well for the Imams of the Muslims, and (3) sticking to their community (jama`a), for their supplications encompass those behind them. The Muslims are brethren: their blood is equivalent, and [even] the lowest of them strives to protect them. They are [one] hand against those who oppose them.
