That may be true for some authors, however it is not true in this case as the author (Sheikh Abdur Rahman ibn Yusuf) has done a good job in being thorough and providing context and background. Also, the purpose of quoting the hadeeth was to further the discussion on the said topic, rather than providing a tafseer of the whole hadeeth. As such, providing only the relevant portion of the hadeeth isn't blameworthy.
That is a good observation. InshaAllaah I will try to find out from Sheikh Abdur Rahman ibn Yusuf whether it's a typo, or that he is using a different referencing method.Now we can see hadith in Page 106 & 107 has same reference number Sahih Muslim(1:181), but referencing 2 different hadith number that i listed out!!!? How? Really hadith in page 106 & Page 107 different hadith? If yes then they should have diffrent hadith number! Right?
And Allaah knows best.
