The World Federation One Stop Fiqh

Ruling 1100

One must perform [the parts of the] prayer in close succession, i.e. he must perform acts such as rukūʿ, sujūd, and tashahhud one after the other, and he must say those things that are said in prayers one after the other in a normal manner. If a person delays between the acts to the extent that it cannot be said he is performing prayers, his prayer is invalid.
