It was narrated from Abu Hurairah that the Messenger of Allah (ﷺ) said: "When Allah created Paradise and Hell, He sent Jibril, peace be upon him, to Paradise and said: 'Look at it and at what I have prepared for its people in it.' He looked at it, then he came back and said: 'By Your Glory, no one will hear of it but he will enter it.' So He commanded that it be surrounded by hardships and said: 'Go and look at it and at what I have prepared for its people in it.' He looked at it and saw that it had been surrounded with hardships. He (Jibril) said: 'By Your Glory, I fear that no one will enter it.' He (Allah) said: 'Go and look at the Fire and at what I have prepared for its people in it.' So he looked at it and parts of it were piled upon other parts. He came back and said: 'By Your Glory, no one will enter it.' So He commanded that it be surrounded with pleasures and said: 'Go and look at it.' So he looked at it and saw that it was surrounded with pleasures. He came back and said: 'By Your Glory, I fear that no one will be saved from it and all will enter it.'"

It was narrated from 'Abdullah bin Yasar, from Qutailah, a woman from Juhainah, that a Jew came to the Prophet (ﷺ) and said: "You are setting up rivals (to Allah) and associating others (with Him). You say: 'Whatever Allah wills and you will,' and you say: 'By the Ka'bah.'" So the Prophet (ﷺ) commanded them, if they wanted to swear an oath, to say: "By the Lord of the Ka'bah;" and to say: "Whatever Allah wills, then what you will."

It was narrated from 'Abdur-Rahman bin Samurah that the Prophet (ﷺ) said: "Do not swear by your forefathers or by false gods (At-Tawaghit)."

It was narrated that Abu Hurairah said: "The Messenger of Allah (ﷺ) said: 'Whoever among you swears and says: By Al-Lat, let him say: La ilaha illallah (There is none worthy of worship except Allah). And whoever says to his companion: Come, let us gamble, then let him give in charity.'"

It was narrated from Mus'ab bin Sa'd that his father said: "We were talking about something, and I had only recently left Jahiliyyah behind, so I swore by Al-Lat and Al-'Uzza. The Companions of the Messenger of Allah (ﷺ) said to me: 'What a bad thing you have said! Go to the Messenger of Allah (ﷺ) and tell him, for we think that you have committed Kufr.' So I went to him and told him, and he said to me: 'Say: La ilaha illallah wahdahu la sharika lah (There is none worthy of worship except Allah alone, without partner) three times, and seek refuge with Allah from the Shaitan three times, and spit dryly to your left three times, and do not say that again.'"

Mus'ab bin Sa'd narrated that his father said: "I swore by Al-Lat and Al-'Uzza and my companions said to me: 'What a bad thing you have said! You have said something horrible.' So I went to the Messenger of Allah (ﷺ) and told him about that. He said: 'Say: La ilaha illallah wahdahu la sharika lah, lahul-mulk wa lahul-hamd wa huwa 'ala kulli shay'in qadir (There is none worthy of worship except Allah with no partner or associate; His is the Dominion, to Him be all praise, and He is able to do all things). Spit to your left three times, seek refuge with Allah from the Shaitan, and do not say that again.'"

Al-Bara' bin 'Azib said: "The Messenger of Allah (ﷺ) commanded us to do seven things: He commanded us to attend funerals, visit the sick, to reply (say: Yarhamuk Allah ) to one who sneezes, to accept invitations, to support the oppressed, to fulfill oaths (when adjured by another) and to return greetings of Salaam."

It was narrated from Abu Al-Ahwas that his father said: "I said: 'O Messenger of Allah, I have a cousin, and I come to him and ask him (for help) but he does not give me anything, and he does not uphold the ties of kinship with me. Then, when he needs me, he comes to me and asks me (for help). I swore that I would not give him anything, nor uphold the ties of kinship with him.' He commanded me to do that which is better and to offer expiation for my oath."

'Ubaid bin 'Umair said: I heard 'Aishah say: "The Prophet (ﷺ) used to stay with Zainab bint Jahsh and drink honey at her house. Hafsah and I agreed that if the Prophet (ﷺ) came to either of us, she would say: 'I detect the smell of Maghafir (a nasty-smelling gum) on you. Have you eaten Maghafir?' He went to one of them and she said that to him. He said: 'No, rather I drank honey at the house of Zainab bint Jahsh, but I will never do it again.' Then the following was revealed: 'O Prophet! Why do you forbid (for yourself) that which Allah has allowed to you' up to: 'If you two turn in repentance to Allah' -'Aishah and Hafsah- 'And (remember) when the Prophet (ﷺ) disclosed a matter in confidence to one of his wives.' refers to him saying: 'No, rather I drank honey.'"

It was narrated that Qais bin Abi Gharazah said: "At the time of the Messenger of Allah (ﷺ) we used to be called Samasir (brokers). The Messenger of Allah (ﷺ) came to us when we were selling and called us by a name that was better than that. He said: 'O merchants (Tujjar), this selling involves lies and (false) oaths, so mix some charity with it.'"

It was narrated that Qais bin Abi Gharazah said: "We used to sell in Al-Baqi, and the Messenger of Allah (ﷺ) came to us. We used to be called Samasir (brokers) but he said: 'O merchants!' And called us by a name that was better than our name. Then he said: 'This selling involves (false) oaths and lies, so mix some charity with it.'"

It was narrated that Qais bin Abi Gharazah said: "The Prophet (ﷺ) came to us when we were in the marketplace and said: 'This marketplace is filled with idle talk and (false) oaths, so mix some charity with it.'"

It was narrated that Qais bin Abi Gharazah said: "In Al-Madinah we used to buy and sell Wasqs (of goods), and we used to call ourselves Samasir (brokers), and the people used to call us like that. The Messenger of Allah (ﷺ) came out to us one day, and called us by a name that was better than that which we called ourselves and which the people called us. He said: 'O Tujjar (traders), your selling involves (false) oaths and lies, so mix some charity with it.'"

'Abdullah bin Ka'b bin Malik said: "I heard Ka'b bin Malik narrating his Hadith about when he stayed behind and did not join the Messenger of Allah (ﷺ) on the campaign to Tabuk. (he said) I said: 'As part of my repentance I want to give my wealth in charity for Allah and His Messenger.' The Messenger of Allah (ﷺ) said: 'Keep some of your wealth for yourself; that is better for you.' I said: 'I will keep for myself my share that is in Khaibar.'"

It was narrated that Abu Hurairah said: "The Messenger of Allah (ﷺ) said: 'Whoever swears an oath and says: "If Allah wills, then he has made an exception."'"

It was narrated from Abu Hurairah, who attributed it to the Prophet: "Sulaiman said: 'I will certainly go around to ninety women tonight, each of whom will bear a child who will fight in the cause of Allah.' It was said to him: 'Say: If Allah wills' but he did not say it. He went around to them but none of them bore a child except for one woman who bore half a person." The Messenger of Allah (ﷺ) said: "If he had said: 'If Allah wills,' he would not have broken his vow, and this would have been a means to help him to get what he wanted."
