Book Name:Namaz Ki Ahmiyat
1. Usually some people are accustomed to scratching continuously in the state of Salah. Remember scratching an itching place 2 times in a Rukn of Salah is allowed scratching an itching place three times in any Rukn nullifies Salah.
Similarly, some people do not regard for Ta’deel-e-Arkaan i.e., they perform Ruku’, Sujood, Qawmah and Jalsah in haste though it is Wajib to stay in these Arkaan long enough to recite ‘سُبحَانَ الله’ and avoiding it, is Makruh Tahreemi which makes Salah Wajib-ul-I’adah i.e., it will be performed again.
Another usual mistake that is noticed is that people do not perform Sajdah properly; in the state of Sajdah, either they lift their feet from the ground or just touch the tips of their toes on the ground. Salah remains invalidate if the requirement of Sajdah would not be fulfilled. It is Fard to touch the middle part of one of the toes to the ground, it is Wajib to touch the middle parts of three of the toes to the ground and it is Sunnah to touch the middle parts of all the 10 toes to the ground.
One of the common mistakes in Salah is that people approach Masjid exactly when it is time of Jama’at, and resultantly they make ablution in a hurry and stand in a row for Salah without rolling down their sleeves. Remember! Salah is Makruh Tahreemi if sleeve is left rolled up to more than half wrist.
Some people, while performing Salah individually, recite in such a low voice that they can’t even listen to it themselves and some even do not move their tongues and recite in heart whereas ruling is that one should recite in such an audible voice that he himself can listen to it. If there is no hindrance e.g. noise or any hearing problem and the voice is very low that the reciter himself can’t listen to it then Salah will get invalidated.
