Assalamualaikum :) Earlier , my dad just taught my siblings about solat jamak and qasar. This is a preparation for our trip this Sunday. So , as you guys know qasar means memendekkan while jamak means menghimpunkan. Okay , so lets make it short. Jamak has two different types. One is jamak takdim and the second is jamak ta'khir.

 Jamak takdim we do it at the first waktu. Like we do solat asar in waktu solat zuhur. Or even solat isyak in waktu solat maghrib. Alaa , kita tunaikan solat tu dalam waktu yang pertama. Faham ? Jamak ta'khir kita tunaikan dalam waktu yang kedua. For example , solat maghrib dalam waktu isyak. Lagi satu , solat zuhur dalam waktu solat Asar. Lebih kurang macam tu. So , I think that is all for now. For futher information --> http://www.ustaznoramin.com/2010/03/niat-syarat-cara-solat-jamak-qasar.html. Inshaa Allah membantu. Goodluck :) Ciao !
