Sahih Muslim
Hadith #390
The same hadith is transmitted from Zuhri with the same chain of transmission. But in the tradition narrated by Ibn 'Uyaina the words are:"" impartial leader and just judge"" and in the tradition narrated by Yunus: the"" judge judging with justice"" and"" impartial leader"" are not mentioned. And in the hadith narrated by Salih like the one transmitted by Laith the words are:"" impartial judge"". And in the hadith transmitted by Ziyad the words are:"" Till one sajda is better than the worldand what it contains. Then Abu Huraira used to say,"" recite"" if you like: Not one of the People of the Book will fail to believe in him before his death
