I perform fard salaah behind my father.
1.Sometimes he makes pronounciation and tajweed mistakes,i have doubts whether to correct him or not.
2.My father also performs salaah faster then I .As a result I am unable to recite Surah Fatiha completely.(During the salaahs when qiraat is read aloud I hear my father reading faster then I .I cannot read qiraat so fast without making makhraj and tajweed mistakes).
3.I am unable to recite the glorification of Allah (SWT) in ruku and sajda due to the salah being read with such speed.(The rukus and sajdah are sufficient in my opinion to read very fast the tasbih).
4.I am unable to observe the tadeel in my fard salah.
Please advise as to the validity of my salah,what I should do in relation to the above numbered four parts of my question.I feel that if it was anyone else leading me in salah i would voice my grievances to them yet it is my father and I feel doubtul as to tell him.
Jazakallah hoo khair
