707. hadíth
وَ قَالَ اَلنَّبِيُّ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ: "مَنْ شَهِدَ عِنْدَنَا بِشَهَادَةٍ ثُمَّ غَيَّرَ أَخَذْنَا بِالْأُولَى وَ طَرَحْنَا اَلْأُخْرَى".
And the Prophet, may Allah (swt) bless him and his family, said: "Whoever testifies before us with a testimony and then changes it, we will accept the first (testimony) and discard the second (testimony)."
