In the New Testament only a select few of people are shown to have had the gift of laying on of hands. The 11 picked by Jesus who was alive at Pentecost in Acts. Matthias chosen by lots and Paul. Not every one of them are ever mentioned doing it, but no one outside of those men are said to do it either. The laying on of hands is the ability to lay your hands on someone and instantly give them the power of the Holy Spirit and God will decide how that power is manifested. Only those men could do that. Paul is one of those men.
But I went into that here.
