Narrated Abu Huraira: The Prophet said, "Whoever swears saying in his oath. 'By Al-Lat and Al-`Uzza,' should say, 'None has the right to be worshipped but Allah; and whoever says to his friend, 'Come, let me gamble with you,' should give something in charity."

Narrated Ibn `Umar: Allah's Apostle had a gold ring made for himself, and he used to wear it with the stone towards the inner part of his hand. Consequently, the people had similar rings made for themselves. Afterwards the Prophet; sat on the pulpit and took it off, saying, "I used to wear this ring and keep its stone towards the palm of my hand." He then threw it away and said, "By Allah, I will never wear it." Therefore all the people threw away their rings as well.

And the Prophet (peace be upon him) said that whoever swears by Al-Lat and Al-‘Uzza (accidentally, without intention or belief), he should recite the statement of Tawheed «لا إله إلا الله» as expiation. (For one who swears such an oath out of forgetfulness or error,) the Prophet (peace be upon him) did not attribute disbelief to him.

Narrated Thabit bin Ad-Dahhak: The Prophet said, "Whoever swears by a religion other than Islam, is, as he says; and whoever commits suicide with something, will be punished with the same thing in the (Hell) Fire; and cursing a believer is like murdering him; and whoever accuses a believer of disbelief, then it is as if he had killed him."

Narrated Abu Hurairah that he heard the Prophet (saws) saying, "Allah decided to test three people from Bani Isra'il. So, He sent an angel who came first to the leper and said, '(I am a traveller) who has run short of all means of living, and I have nobody to help me except Allah, and then with your help.'" Abu Hurairah then mentioned the complete narration.

And Ibn Abbas (may Allah be pleased with them both) said that Abu Bakr al-Siddiq (may Allah be pleased with him) said: By Allah, O Messenger of Allah! Tell me, where did I make a mistake in interpreting (the dream)? The Prophet (peace and blessings of Allah be upon him) said: Do not swear an oath.

Narrated Al-Bara: The Prophet ordered us to help others to fulfill the oaths.

Narrated Usama: Once a daughter of Allah's Apostle sent a message to Allah's Apostle while Usama, Sa`d, and Ubai were (sitting there) with him. She said, (in the message); My child is going to die; please come to us." Allah's Apostle returned the messenger and told him to convey his greetings to her, and say, "Whatever Allah takes, is for Him and whatever He gives is for Him, and everything with Him has a limited fixed term (in this world): so she should be patient and hope for Allah's reward." Then she again sent for him swearing that he should come; so The Prophet got up, and so did we. When he sat there (at the house of his daughter), the child was brought to him, and he took him into his lap while the child's breath was disturbed in his chest. The eyes of Allah's Apostle started shedding tears. Sa`d said, "What is this, O Allah's Apostle?" The Prophet said, "This is the mercy which Allah has lodged in the hearts of whoever He wants of His slaves, and verily Allah is merciful only to those of His slaves who are merciful (to others).'

Narrated Abu Huraira: Allah's Apostle said, "Any Muslim who has lost three of his children will not be touched by the Fire except that which will render Allah's oath fulfilled."

Narrated Haritha bin Wahb: I heard the Prophet saying, "Shall I tell you of the people of Paradise? They comprise every poor humble person, and if he swears by Allah to do something, Allah will fulfill it; while the people of the fire comprise every violent, cruel arrogant person."
