Narrated Al-Numan bin Bashir: I heard the Messenger of Allah ﷺ say: What is lawful is clear and what is unlawful is clear, but between them are certain doubtful things. I give you an example for this. Allah has a preserve, and Allah's preserve is the things He has declared unlawful. He who pastures (his animals) round the preserve will soon fall into it. He who falls into doubtful things will soon be courageous.

Narrated Al-Numan bin Bashir: I heard Messenger of Allah ﷺ say: But between them are certain doubtful things which many people do not recognize. He who guards against doubtful things keeps his religion and his honor blameless, but he who falls into doubtful things falls into what is unlawful.

Narrated Abu Hurairah: The Prophet ﷺ said: A time is certainly coming to mankind when only the receiver of usury will remain, and if he does not receive it, some of its vapour will reach him. Ibn Isa said: Some of its dust will reach him.

Asim ibn Kulayb quoted his father's authority for the following statement by one of the Ansar: We went out with the Messenger of Allah ﷺ to a funeral, and I saw the Messenger of Allah ﷺ at the grave giving this instruction to the grave-digger: Make it wide on the side of his feet, and make it wide on the side of his head. When he came back, he was received by a man who conveyed an invitation from a woman. So he came (to her), to it food was brought, and he put his hand (i. e. took a morsel in his hand); the people did the same and they ate. Our fathers noticed that the Messenger of Allah ﷺ was moving a morsel around his mouth. He then said: I find the flesh of a sheep which has been taken without its owner's permission. The woman sent a message to say: Messenger of Allah, I sent (someone) to an-Naqi' to have a sheep bought for me, but there was none; so I sent (a message) to my neighbour who had bought a sheep, asking him to send it to me for the price (he had paid), but he could not be found. I, therefore, sent (a message) to his wife and she sent it to me. The Messenger of Allah ﷺ said: Give this food to the prisoners.
