The Sayings And Preaching of Al-Imam Ali (p.b.u.h)
Hadith n. 203
203. Amir al-mu’minin, peace be upon him, said: O people, fear Allah Who is such that when you speak He hears and when you conceal (a secret) He knows it. Prepare yourself to meet death which will overtake you even if you run away, catch you even if you stay and remember you even if you forget it.
Hadith n. 204
204. Amir al-mu’minin, peace be upon him, said: If someone is not grateful to you, that should not prevent you from good actions, because (possibly) such a person will feel grateful about it who has not even drawn any benefit from it, and his gratefulness will be more than the ingratitude of the denier; And Allah loves those who do good. (Qur’an, 3:134,148; 5:93)
Hadith n. 205
205. Amir al-mu’minin, peace be upon him, said: Every container gets narrower according to what is placed in it except the container of knowledge which expands instead.
Hadith n. 206
206. Amir al-mu’minin, peace be upon him, said: The first reward the exerciser of forbearance gets is that people become his helpers against the ignorant.
Hadith n. 207
207. Amir al-mu’minin, peace be upon him, said: If you cannot forbear, feign to do so because it is seldom that a man likens himself to a group and does not become as one of them.47
