That ‘Abd al-Rahman b.’Awf said: I heard the Messenger of Allah (ﷺ) say: When you hear that it is breaking out in a certain territory, do not go there. If it breaks out in the territory you are in, do not go out fleeing away from it. By “it” he referred to the plague.
The Prophet (ﷺ) as saying: If anyone buys sheep whose udders have been tied up, he has option for three days: he may return it if he desires with a sa’ of any grain, not (necessarily) wheat.
The Messenger of Allah (ﷺ) sued to teach them the following words in the case of alarm: I seek refuge in Allah’s perfect words from His anger, the evil of His servants, the evil suggestions of the devils and their presence. Abdullah ibn Amr used to teach them to those of his children who had reached puberty, and he wrote them down (on some material) and hung on the child who had not reached puberty.
