Can one use the miswaak during the khutbah?
Question

                When should a person refrain from playing with pebbles on the ground and using miswaak during the Jumu’ah prayers? Is it from the time when the imaam ascends the minbar or from the beginning of the khutbah? Because I see many people who do not stop using the miswaak until after the imaam has started the khutbah, and some of them continue to use the miswaak during the khutbah.
Praise be to Allah. 
          The Sunnah is to pay attention to the khutbah and to 
          stop using the miswaak or fidgeting in any other way from the moment 
          the khutbah begins until it is over, acting in accordance with the saheeh 
          ahaadeeth that have been narrated to that effect. 
 
          But if a person enters the mosque when the khateeb is 
          preaching he should pray (two rak’ahs) to “greet the mosque” before 
          he sits down, because the Prophet 
          
          (peace and blessings of Allaah be upon him) said: “When any one of you 
          comes on a Friday and the imaam is preaching, let him pray two rak’ahs 
          and make them short.” (Narrated by al-Bukhaari,  al-Jumu’ah, 
          1100; Muslim, al-Jumu’ah, 1449. This version was narrated by Muslim).
