فَمَنْ أَظْلَمُ مِمَّنِ ٱفْتَرَىٰ عَلَى ٱللَّهِ كَذِبًا أَوْ كَذَّبَ بِـَٔايَٰتِهِۦٓ ۚ أُو۟لَٰٓئِكَ يَنَالُهُمْ نَصِيبُهُم مِّنَ ٱلْكِتَٰبِ ۖ حَتَّىٰٓ إِذَا جَآءَتْهُمْ رُسُلُنَا يَتَوَفَّوْنَهُمْ قَالُوٓا۟ أَيْنَ مَا كُنتُمْ تَدْعُونَ مِن دُونِ ٱللَّهِ ۖ قَالُوا۟ ضَلُّوا۟ عَنَّا وَشَهِدُوا۟ عَلَىٰٓ أَنفُسِهِمْ أَنَّهُمْ كَانُوا۟ كَٰفِرِينَ
Who doeth greater wrong than he who inventeth a lie concerning Allah or denieth Our tokens. (For such) their appointed portion of the Book (of destiny) reacheth them till, when Our messengers come to gather them, they say: Where (now) is that to which ye cried beside Allah? They say: They have departed from us. And they testify against themselves that they were disbelievers.
Surah Al-A'raaf(7:37)
Sahih al-Bukhari
Hiring
Chapter: Employment up to midday
Narrated Ibn `Umar:
The Prophet (ﷺ) said, "Your example and the example of the people of the two Scriptures (i.e. Jews and Christians) is like the example of a man who employed some laborers and asked them, 'Who will work for me from morning till midday for one Qirat?' The Jews accepted and carried out the work. He then asked, Who will work for me from midday up to the `Asr prayer for one Qirat?' The Christians accepted and fulfilled the work. He then said, 'Who will work for me from the `Asr till sunset for two Qirats?' You, Muslims have accepted the offer. The Jews and the Christians got angry and said, 'Why should we work more and get lesser wages?' (Allah) said, 'Have I withheld part of your right?' They replied in the negative. He said, 'It is My Blessing, I bestow upon whomever I wish .'
