Re: Looking for info on combining salah
the combining sala'h is for those people who know that they would be on journey and most probably will miss out the sala'hs. But, some scholars also say that you can combine sala'hs once in while because there's a hadith which shows that Prophet(SAW) did that. However, in general, praying all the sala'hs during the right times is correct view derived from Sunna'h. For delaying or missing out a sala'h the only excuseses that are acceptable and found in Prophet(SAW) hadith are that person either was sleeping or forgot. But people who are sick and aren't able to offer their sala'h will also be excused and those who will be joureny.
The wordly excuses doesn't work for comibing two sala'hs together, inshAllah make an effor and offer them during the right times
For asr and Zuhr and Isha, you only offer 2 fard raka'hs each when you're combining with another salah and will be on journey. Basically, for example if you combine Asr with zuhr, then offer full zuhr sala'h and offer 2 fard raka'hs for asr. For maghrib, you offer all the 3 fard raka'hs. I recently found out that you can cut down the 4 fard raka'hs to two before i used to offer all 4 and i thought that's how about to go. On Fridays when i go back home from university, i miss out my asr and maghrib, so i combine them with Juma'h Salah.
