Abu Huraira narrated, “The Messenger of Allah ﷺ said, 'People will keep wondering till it will be said, ‘Allah created all things but who created Allah?’ Whoever finds something like that should say, ‘I believe in Allah.’” In another narration, “The devil comes to one of you and says, ‘Who created the sky? Who created the Earth?’ Then you answered, ‘Allah.’” It mentioned the same content as the first narration but added, “ … and his messengers.”.
Commentary : The pure law of Islam established the relationship among people on the basis of honesty. Muslims are honest about their rights, but some may betray and falsely swear sacred oaths to take people's properties, especially if the proof of the right holder is not clear. In this hadith, the Prophet (ﷺ) confirmed that if a Muslim falsely swears to take people's properties, Allah will prevent him from entering Paradise and make him enter Hell as a punishment for his lying and depriving people of their rights by false oaths. This will be his punishment on condition that he thinks this act is permissible and does not return the property to its owner. Islam considers it a grave sin, for the false oath is one of the major sins, and the Islamic rulings are based on apparent proofs and oaths, even if the person to whom the ruling was made was a liar. As a result, a man asked the Prophet (ﷺ) if the one who committed this sin would enter Hell even if the right unjustly taken was trivial. The Prophet replied that he would definitely enter Hell even if it were a small stick from the Arak tree from which the siwak is taken. The oppressor should not underestimate his small sins because lots of people will be punished for their small sins. There is a saying that confirms that most of the worldly fire is from small sparks. This is supported by Allah's saying, "Indeed, those who exchange the covenant of Allah and their [own] oaths for a small price will have no share in the Hereafter, and Allah will not speak to them or look at them on the Day of Resurrection, nor will He purify them; and they will have a painful punishment." (Aal-Imran: 77) This hadith contains the following benefits: (1) It includes a stern warning against taking people's properties by false oaths and (2) There is no difference between grave and trivial sins as long as they both oppress people..
