In Salah it is necessary to move the lips and tongue when reciting the different types of supplications, eg: Takbir Tahrimah (The Takbir to commence Salah), Qiraat, Tashahud, Salam, etc. If one does not verbally recite the necessary words by moving the lips and tongue but merely recites it in his heart, the Salah will be invalid.
The area from the naval up to and including the knee of a man is part of his Aurah (incumbent to conceal) and accordingly it is impermissible for a man to expose this part of his body. Likewise it is impermissible for one to gaze at the exposed part of a man's body that should be concealed.
Salah requires maximum humility, dignity and grace. Hence, whilst approaching Salah, the Musalli should be fully composed and dignified. Running towards the Salah panting and grasping for breath due to hastening for Salah is contrary to the etiquette of Salah.
There is a common misunderstanding that three Talaaqs have to be uttered for the divorce to be valid and that the Talaaq does not occur by giving one or two Talaaqs. This is absolutely wrong! Giving three divorces at once is a great sin and causes the marriage to be absolutely terminated, with no room for reconciliation.
It is necessary for men to cover the area between the naval and knees at all times. Exposing this area is sinful and if it is exposed during Salaah, the Salaah is invalid. Many modern fashion trends cause parts of this area, more specifically parts of the hip and below, to be exposed when one goes into Ruku or Sajda. Brothers are requested to take heed and wear modest clothing.
