The ruling on the prayer of the ma'mum who did not complete the final tashahhud

Question:
Your Eminence the Shaykh, the questioner says: I love you for the sake of Allah. He says: I experience hesitation in some of the words of the tashahhud, to the point that the imam has already said the taslim and I have not finished the tashahhud. So, am I required to complete it after the imam's taslim, or should I say the taslim with him? And am I permitted to lead people in prayer as an imam, or not? I ask Your Eminence to supplicate for my healing. May Allah reward you.

Answer:
Love for the sake of Allah is among the best of the means of nearness to Allah, and we say: May Allah love you, the One who has made you love [others]. The Prophet (peace and blessings be upon him) said: . It is mentioned therein: "May Allah love those who love one another for His sake." The hadith says: Allah, Mighty and Majestic, said: "My love is obligatory for those who love one another for My sake, and who meet for My sake, and who part for My sake." As for what happened to you of waswas (whispers) until the imam says the taslim before you finish the tashahhud, this is from Shaytan. You must be wary of that, and seek refuge in Allah from Shaytan, and spit to your left three times. Say "I seek refuge in Allah from Shaytan" three times, for this is among the causes of healing. And complete the tashahhud, even if it is after the imam's taslim. Do not stand up from the tashahhud. Send blessings upon the Prophet (peace and blessings be upon him), and recite the testimony of faith, then say the taslim. And strive against your self in this. Seek refuge in Allah from Shaytan when waswas occurs, whether in the tashahhud or otherwise. You must be wary of the enemy of Allah, for he is eager to destroy you. Allah the Exalted said:
