Narrated Anas bin Malik (rad):

The Prophet (ﷺ) had blood extracted from his body and offered the prayer and did not perform (a new) ablution. [Reported by Ad-Daraqutni who graded it Da’if (weak)].

وَعَنْ أَنَسِ]بْنِ مَالِكٍ] ‏- رضى الله عنه ‏- { أَنَّ اَلنَّبِيَّ ‏- صلى الله عليه وسلم ‏-اِحْتَجَمَ وَصَلَّى, وَلَمْ يَتَوَضَّأْ } أَخْرَجَهُ اَلدَّارَقُطْنِيُّ, وَلَيَّنَه ُ [1]‏ .‏
