20-12 حدثنا أبي رضي الله عنه قال: حدثنا سعد بن عبد الله، عن محمد بن عيسى ابن عبيد اليقطيني قال: حدثنا جماعة من أصحابنا رفعوه إلى أميـر المؤمنيـن عليـهالسلام قال: قال رسول الله صلى الله عليه وآله:تعلموا العلم فإن تعلمه حسنة، ومدراسته تسبيح، والبحث عنه جهاد، وتعليمه من لا يعلمه صدقة، وبذله لاهله قربة، لانه معالم الحلال والحرام، وسالك بطالبه سبيل الجنة، وهو أنيس في الوحشة، وصاحب في الوحدة، ودليل على السراء والضراء، وسلاح على الاعداء، وزين للاخلاء، يرفع الله به أقواما يجعلهم في الخير أئمة يقتدى بهم، ترمق أعمالهم، وتقتبس آثارهم، وترغب الملائكة في خلتهم، يمسحونهم في صلاتهم بأجنحتهم، ويستغفر لهم كل شيء حتى حيتان البحور وهوامها، وسباع البر وأنعامها، لان العلم حياة القلوب، ونور الابصار من العمى، وقوة الابدان من الضعف، ينزل الله حامله منازل الاخيار، ويمنحه مجالس الابرار في الدنيا والآخرة، بالعلم يطاع الله ويعبد، وبالعلم يعرف الله ويؤخذ، وبالعلم توصل الارحام، وبه يعرف الحلال والحرام،والعلم امام العمل والعمل تابعه، يلهمه الله السعداء ويحرمه الاشقياء

20-12 (The compiler of the book narrated) that his father - may God be pleased with him - narrated that Sa’ed ibn Abdullah quoted on the authority of Muhammad ibn Isa ibn Ubayd al-Yaqtayni who narrated a group of friends who linked it up to the Commander of the Faithful Imam Ali(MGB) that God’s Prophet (MGB) said, “Acquire knowledge since learning is a good deed, teaching equals saying God’s glorifications, and discussing about knowledge equals participating in a holy war. Teaching knowledge to the one who doesn’t know it is giving charity. Granting knowledge to the proper persons brings God’s pleasure, since one knows the lawful and the unlawful using knowledge and knowledge would lead its seeker to Paradise. Knowledge is a guide in case of fear; it is a companion in case of loneliness; it is a guide in case of hardships; it is a weapon against the enemies; and an ornament in the presence of friends. God promotes some people by means of knowledge to such a high rank that they are the leaders of goodness and must be obeyed. Their deeds must be taken into consideration and their works must be followed. The angels are inclined to be their friends and they anoint them with their own wings while they pray. Everything including the fish in the sea, the beasts in the desert and the quadrupeds ask for forgiveness for them since knowledge brings life to the hearts and light to the eyes and power against sluggishness. God opens the doors to the homes of the good people for the learned men. He grants them association with the good ones in this world and in the Hereafter. God is obeyed and served by means of knowledge. God is recognized as One by means of knowledge. The bonds of relationship are fastened by means of knowledge. What is lawful and unlawful is recognized by means of knowledge. Knowledge is the prelude to action. Any action follows knowledge. God inspires it to the blessed ones and deprives the miserable ones from it.’
