There are some particles which are generally regarded as conditionals, e.g. (لمَّا) and (كلَّما). However, they express a temporal relationship rather than a condition. There are still 2 actions that are related to each other by a temporal relationship, for example:
لمَّا سافرَ أخي، سافرتُ معه.
“When my brother traveled, I traveled with him.”
كلَّما سافرَ أخي، سَافرتُ معه.
“Whenever my brother traveled, I traveled with him.”
لمَّا يسافرُ أخي، أسافرُ معه.
“When my brother travels, I travel with him.”
كلَّما يسافرُ أخي، أسافرُ معه.
“Whenever my brother travels, I travel with him.”
Other particles that are used in this way express a spacial relationship, for example:
حيثما سافرَ أخي، سافرتُ معه.
“Wherever my brother traveled, I traveled with him.”
أينما سافرَ أخي، سافرتُ معه.
“Wherever my brother traveled, I traveled with him.”
حيثما يسافرُ أخي، أسافرُ معه.
“Wherever my brother travels, I travel with him.”
أينما يسافرُ أخي، أسافرُ معه.
“Wherever my brother travels, I travel with him.”
