Salaah

Attending only Fajr and Esha in the Musjid due to living far away

Q: I live 10 minutes from a mosque and because of this distance I spend almost 2 hours every day walking to and from the mosque to the five daily prayers.  I am I student and need as much time as possible for my studies. Would it be permissable for me, in order to save time, to attend only Fajr and Isha in the mosque (because of the big virtue of praying these prayers in the mosque) and pray the rest of the prayers alone at home?

Qadha Salaah after Asr

Q: With the Mercy of Allah, I have recently starting reading all my qadhaa salaah that i have missed since i became baaligh, this being a few years of salaah. I am able to read my fajr qadhaa before leaving for work, then my zohr qadhaa after performing zohr salaah, magribh qadhaa after magribh and esha after esha salaah. I have not been able to fit in my asr salaah as I am aware that one cannot perform any salaah afer asr. However, I have been advised, that if i am performing my qadhaa salaah then i can perform it after asr. Is this correct or permissable?

Reading different Surahs each day in the five Salaats

Q:

  1. Is it imperative to read diff rent surats each day in the five salaats? Would salaat be valid if one continuously recites the same surats only.  For example, in the Maghrib salaat each day, one habitually recites sura Falaq in the first rakaat and sura Naas in the second rakaat. 
  2. Can Ayatul Kursi be recited in place of a sura in salaat or is it necessary to add at least two ayaats before or after ayaatul Kursi?
