Assalaamu Alaikum,
Q:Is it permissible for a husband to lead his wife in salaah?
Wa Alaikum Assalaam,
A: Yes, it is permissible. However, they must not stand close to each other that will cause her body to touch him while they are together in the same salaah. She should stand behind.
And Allah Knows Best.
