In the Name of Allah, the Most Gracious, the Most Merciful. As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh with due respectable. My name is [private]. I would like to get your guidance. Please reply, can nikkah on Skype or phone is it permissible?
It is unreliable as you need a true and actual witnessing and attendance, not virtual or telecast. Therefore nikah by phone, Skype and similar media is invalid unless it is witnessed and attended in the flesh by the obligatory parties to a valid contract or their lawful representatives, and Allah knows best.
