The Sayings And Preaching of Al-Imam Ali (p.b.u.h)
Hadith n. 208
208. Amir al-mu’minin, peace be upon him, said: Whoever takes account of his self is benefited, and whoever remains neglectful of it suffers. Whoever fears remains safe; whoever takes instruction (from things around) perceives; and whoever perceives gains understanding, and whoever gains understanding secures knowledge.
209. Amir al-mu’minin, peace be upon him said: The world will bend towards us after having been refractory as the biting she-camel bends towards its young. Then Amir al-mu’minin recited the verse:
And intend We to bestow (Our) favour upon those who were considered weak in the land, and to make them the Imams (guides in faith), and to make them the heirs. (Qur’an, 28:5) 48
210. Amir al-mu’minin, peace be upon him, said: Fear Allah like the one who prepares himself after extracting himself (from worldly affairs) and after getting ready in this way makes effort; then he acts quickly during the period of this life, hastens in view of the dangers (of falling into error) and has his eye on proceeding towards the goal, on the end of his journey and on the place of his (eventual) return.
Hadith n. 211
211. Amir al-mu’minin, peace be upon him, said: Generosity is the protector of honour; forbearance is the bridle of the fool; forgiveness is the levy of success; disregard is the punishment of him who betrays; and consultation is the chief way of guidance. He who is content with his own opinion faces danger. Endurance braves calamities while impatience is a helper of the hardships of the world. The best contentment is to give up desires. Many a slavish mind is subservient to overpowering longings. Capability helps preservation of experience. Love means well-utilized relationship. Do not trust one who is grieved.
Hadith n. 213
213. Amir al-mu’minin, peace be upon him, said: Ignore pain otherwise you will never be happy. (Or according to another reading): Ignore pain and grief; you will ever be happy. 50
