It is permissible to get the attention of one who is speaking during the khutbah by means of a gesture. The Sahabah did that and the Prophet (blessings and peace of Allah be upon him) approved of what they did.

It is permissible for the workplace to deduct something from the employee’s salary to pay off a debt that he owes to them, provided that that is done with the consent of both parties and provided that it will not add up to more than what is owed.
