The 5 hadiths:
Volume 4, Book 56, Number 665:
Allah’s Apostle said, “Your period (i.e. the Muslims’ period) in comparison to the periods of the previous nations, is like the period between the ‘Asr prayer and sunset. And your example in com- parison to the Jews and the Christians is like the example of a person who employed some laborers and asked them, ‘Who will work for me till midday for one Qirat each?’ The Jews worked for half a day for one Qirat each. The person asked, ‘Who will do the work for me from midday to the time of the ‘Asr (prayer) for one Qirat each?’ The Christians worked from midday till the ‘Asr prayer for one Qirat. Then the person asked, ‘Who will do the work for me from the ‘Asr till sunset for two Qirats each?’ ” The Prophet added, “It is you (i.e. Muslims) who are doing the work from the Asr till sunset, so you will have a double reward. The Jews and the Christians got angry and said, ‘We have done more work but got less wages.’ Allah said, ‘Have I been unjust to you as regards your rights?’ They said, ‘No.’ So Allah said, ‘Then it is My Blessing which I bestow on whomever I like.
Volume 1, Book 10, Number 533:
The Prophet said, “The example of Muslims, Jews and Christians is like the example of a man who employed laborers to work for him from morning till night. They worked till mid-day and they said, ‘We are not in need of your reward.’ SO the man employed another batch and said to them, ‘Com- plete the rest of the day and yours will be the wages I had fixed (for the first batch). They worked Up till the time of the ‘Asr prayer and said, ‘Whatever we have done is for you.’ He employed another batch. They worked for the rest of the day till sunset, and they received the wages of the two former batches.”
Volume 3, Book 36, Number 468:
The Prophet 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 Christi- ans 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 with-held part of your right?’ They replied in the negative. He said, ‘It is My Blessing, I bestow upon whomever I wish
Volume 3, Book 36, Number 469:
Allah’s Apostle said, “Your example and the example of Jews and Christians is like the example of a man who employed some laborers to whom he said, ‘Who will work for me up to midday for one Qirat each?’ The Jews carried out the work for one Qirat each; and then the Christians carried out the work up to the ‘Asr prayer for one Qirat each; and now you Muslims are working from the ‘Asr prayer up to sunset for two Qirats each. The Jews and Christians got angry and said, ‘We work more and are paid less.’ The employer (Allah) asked them, ‘Have I usurped some of your right?’ They replied in the negative. He said, ‘That is My Blessing, I bestow upon whomever I wish.’ ”
Volume 3, Book 36, Number 471:
The Prophet said, “The example of Muslims, Jews and Christians is like the example of a man who employed laborers to work for him from morning till night for specific wages. They worked till mid- day and then said, ‘We do not need your money which you have fixed for us and let whatever we have done be annulled.’ The man said to them, ‘Don’t quit the work, but complete the rest of it and take your full wages.’ But they refused and went away. The man employed another batch after them and said to them, ‘Complete the rest of the day and yours will be the wages I had fixed for the first batch.’ So, they worked till the time of ‘Asr prayer. Then they said, “Let what we have done be an- nulled and keep the wages you have promised us for yourself.’ The man said to them, ‘Complete the rest of the work, as only a little of the day remains,’ but they refused. Thereafter he employed another batch to work for the rest of the day and they worked for the rest of the day till the sunset, and they received the wages of the two former batches. So, that was the example of those people (Muslims) and the example of this light (guidance) which they have accepted willingly.
