I taught some persons of the people of Suffah writing and the Qur'an. A man of them presented to me a bow. I said: It cannot be reckoned property; may I shoot with it in Allah's path? I must come to the Apostle of of Allah (ﷺ) and ask him (about it). So I came to him and said : Messenger of Allah (ﷺ), one of those whom I have been teaching writing and the Qur'an has presented me a bow, and as it cannot be reckoned property, may I shoot with it in Allah's path? He said: If you want to have a necklace of fire on you, accept it.

Some of the Companions of Prophet (ﷺ) went on a journey. They encamped with a clan of the Arabs and sought hospitality from them, but they refused to provide them with any hospitality. The chief of the clan was stung by a scorpion or bitten by a snake. They gave him all sorts of treatment, but nothing gave him relied. One of them said: Would that you had gone to those people who encamped with you ; some of them might have something which could give you relief to your companion. (So they went and) one of them said: Our chief has been stung by a scorpion or bitten by a snake. We administered all sorts of medicine but nothing gave him relief. Has any of you anything, i.e. charm, which gives healing to our companion. One of those people said: I shall apply charm; we sought hospitality from you, but you refused to entertain us. I am not going to apply charm until you give me some wages. So they offered them a number of sheep. He then came to and recited Faithat-al-Kitab and spat until he was cured as if he were set free from a bond. Thereafter they made payment of the wages as agreed by them. They said: Apportion (the wages). The man who applied the charm said: Do not do until we come to the Messenger of Allah (ﷺ) and consult him. So they came to the Messenger of Allah (ﷺ) next morning and mentioned it to him. The Messenger of Allah (ﷺ) said: From where did you learn that it was a charm ? You have done right. Give me a share along with you.

You have brought what is good from this man. Then they brought a lunatic in chains. He recited Surat al-Fatihah over him three days, morning and evening. When he finished, he collected his saliva and then spat it out, (he felt relief) as if he were set free from a bond. They gave him something (as wages). He then came to the Prophet (ﷺ) and mentioned it to him. The Messenger of Allah (ﷺ) said: Accept it, for by my life, some accept it for a worthless charm, but you have done so far a genuine one.
