What is the ruling on interlacing one's fingers if it is done in the mosque?

Interlacing fingers is prohibited for anyone going to the mosque for prayer or awaiting prayer, because he is considered to be in the state of prayer. This is part of the etiquette of going to the mosque and refraining from fidgeting while awaiting prayer. However, interlacing fingers after the prayer has concluded or at a time other than prayer inside the mosque is permissible. Spreading fingers is disliked during prayer and indicates a lack of devotion.
