Ibraaheem Ibn Bash-shaar [rahimahullaah] said: Ibraaheem Ibn Adham [rahimahullaah] watched a man who was speaking to another man; so he [i.e. the man] got so angry that he uttered an ugly statement. So Ibraaheem said to him: O such and such! Fear Allaah and it is obligatory that you keep quiet, exercise forbearance and restraint; so the man kept quiet. Then Ibraaheem said to him: It has reached me that Ahnaf Ibn Qais [rahimahullaah] said: We frequently went to Qais Ibn Aasim [rahimahullaah] to learn forbearance from him, just as we frequently went to the scholars to seek knowledge. So he [i.e. the man] said [to ibraaheem]: You don’t have to repeat it [i.e. what you have said is enough as an admonition etc]. [Taareekh Dimashq 26/219]
