[Machine] About Masrooq and Shurayh, they said that a testimony cannot be accepted on top of another testimony in a hadd punishment, and it cannot be guaranteed in a hadd punishment.  

عَنْ مَسْرُوقٍ وَشُرَيْحٍ أَنَّهُمَا قَالَا لَا تَجُوزُ شَهَادَةٌ عَلَى شَهَادَةٍ فِي حَدٍّ وَلَا يُكْفَلُ فِي حَدٍّ  

[Machine] "Ata and Tawus said: It is not permissible to have a testimony upon another testimony in a legal punishment (Hadd). We were narrated from Ash-Sha'bi and Ibrahim regarding the prevention of doubts in determining legal punishments in the Book of Hadd."  

عَنْ عَطَاءٍ وَطَاوُسٍ قَالَا لَا تَجُوزُ شَهَادَةٌ عَلَى شَهَادَةٍ فِي حَدٍّ وَرُوِّينَا عَنِ الشَّعْبِيِّ وَإِبْرَاهِيمَ وَقَدْ مَضَتِ الْأَخْبَارُ فِيهِ فِي دَرْءِ الْحُدُودِ بِالشُّبُهَاتِ فِي كِتَابِ الْحُدُودِ
