BENEFIT 2:

الأمور التي تجري فيها الأحكام الخمسة Actions during prayer vary according to the 5 rulings: 1⃣. It is Wājib (obligatory) if the validity of the prayer depends on it. Eg. During the prayer a man remembers that his turban has urine stains; if he removes this turban immediately - he can continue praying and the prayer is valid, otherwise the prayer becomes invalid. Thus, this act of removing the turban is wājib in this case. Eg. A sister's hijāb loosens and her hair starts to show; she must tuck the hair in and tighten her hijab immediately in order for the prayer to be valid. Otherwise, exposing her ’Awrah intentionally will render the prayer invalid. Eg. Preventing a woman from walking infront of you during the prayer (if you are praying alone or you the imām). Eg. Someone trustworthy informs you that you are facing the wrong direction, you must turn towards the correct Qiblah direction. 2⃣. It is Ḥarām (forbidden) if it will render the prayer invalid. Eg. Eating, drinking, talking, laughing...intentionally Eg. Adding an extra rukn or wajib act intentionally. Eg. Constant, repetitive movements without there being any need...constantly playing with the beard 3⃣. It is Mustaḥabb (recommended) if there's evidence to indicate that such action is recommended during the prayer Eg. Responding to salām by raising the hand Eg. Spittling thrice to the left when experiencing bad thoughts in Ṣalāh 4⃣. It is Mubāḥ (allowed) if there's a need Eg. Scratching an itch in order to cool it down 5⃣.
