Sheikh Ahmad Kutty, a senior lecturer and Islamic scholar at the Islamic Institute of Toronto, Ontario, Canada, states: “The time between the two khutbahs on Friday is the time for worshipers to engage in dhikr (remembrance of Allah) and du`a’ (supplication), so they must not be disturbed at this time by soliciting donations. According to sound traditions, once the imam has climbed the pulpit until he has finished the sermon, no distractions are permissible, for any such acts are akin to indulging in laghw (idle talks or action), which would amount to invalidating one’s jumu`ah. The Prophet’s Companions took this matter so seriously that they would even refuse to answer an important question from one another at this time. The Prophet (peace and blessings be upon him) also indicated the seriousness of the matter when he said, “When the imam climbs the pulpit, the angels close their register in preparation for listening to the sermon!”
It should be clear from the above that once the imam has climbed the pulpit until he has finished the sermon, it is imperative that we abstain from all extraneous activities. To do otherwise will be interfering with the format of this important worship.
Having said this, I must rush to add: It is best that we use other acceptable times to solicit funds: Either before the khutbah or after the Prayer and du`a’, etc. By doing what is right, we stand to gain immense blessings. May Allah guide our steps. Ameen.”
