The Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, further stated: "If this happens deliberately, then he is required to purify himself and start the prayer again from its beginning." This establishes that intentional actions such as speaking deliberately, turning away from the qibla intentionally, or invalidating the state of purity (hadath) during prayer necessitate starting the prayer anew. Further clarification on this matter, with sufficient evidence, will be mentioned later, if Allah سبحانه وتعالى willing.
