5. He said: Abul Hasan ‘Ali ibn Malik al-Nahwi recited the following verses to me from Abu al-Husayn, Muhammad ibn Abdillah al-Ma’mooni, who said my father recited for me, verses by al-Mamoon: "Protect yourself from things you loathe, by patience, for perchance, there may be a day when you will not see anything you detest; Many a times, a man remains hidden, while eyes vie to have a sight of him; but he is concealed; Many a times, a literate man spares his tongue fearing the answer, and that silence becomes eloquent; Many a times, a dignified man smiles in pain, While his heart groans with its burn." And may Allah bless our master Muhammad, the Prophet, and his pure progeny.
