4/16. Chapter:
The Tashah-hud In The Prayer
Sahih Muslim
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَابْنُ، بَشَّارٍ قَالاَ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ مَنْصُورٍ، بِهَذَا الإِسْنَادِ مِثْلَهُ وَلَمْ يَذْكُرْ " ثُمَّ يَتَخَيَّرُ مِنَ الْمَسْأَلَةِ مَا شَاءَ " .
Shu'ba has narrated this on the authority of Mansur with the same chain of transmitters, but he made no mention of this: " Then he may choose any supplication which pleases him."
