باب السَّهْوِ فِي الصَّلاَةِ وَالسُّجُودِ لَهُ ‏
Sahih Muslim 572 f

This hadith has been reported by Mansur with the same chain of transwitters and he said:

" He should aim at what is according to him correct."
وَحَدَّثَنَاهُ يَحْيَى بْنُ يَحْيَى، أَخْبَرَنَا فُضَيْلُ بْنُ عِيَاضٍ، عَنْ مَنْصُورٍ، بِهَذَا الإِسْنَادِ وَقَالَ ‏ "‏ فَلْيَتَحَرَّ الَّذِي يُرَى أَنَّهُ الصَّوَابُ ‏"‏ ‏.‏
