valid prayer

As-Salamu `Alaykum. Sometimes when I pray Dhur and `Asr I forget the Tashahhud in between (i.e. the Tashahhud between 2nd and 3rd Rak`ah). Facing this, what shall I do? Do I have to repeat the prayer once again. Jazakum Allah Khayran.

Respected scholars, as-salamu `alaykum. I have a question that has been bothering me for years.  I believe I suffer from anxiety that manifests in extreme sweating on my head.  During salah (ritual Prayer), usually when in congregation, I cannot control the sweating and it literally drips off my head and onto my face.  Is it permissible for me to carry a handkerchief with me during salah to wipe the sweat? Jazakum Allahu Khayran.

Salaamz,thank you very much for prviding this great services to muslims everywhere.   My question is: When I perform my prayers, I perform do not perform them hastely.  I try to recite the words carefully and pay attention to what I am saying. When I go to the masjid to pray Isha, the imam recites the 2 sunnah and 2 nafil (After Faraz) a lot faster than my pace of reciting the shortest surahs.  So I hasten to finish the 2 sunnah and 2 nafil so I can join the witr prayers. What is the best course of action so I can pray my namaz without hastening my prayers?Jazak Allah.Junaid
