Bismillah walhamdulillah was salaatu wassalaamu alaa rasoolullah, wa ba'ad
Here is a beneficial lecture of Shaykh Ahmed an-Najmi rahimahullah entitled "Knowledge precedes Speech". Towards the end there are questions and answers and one of the question is regarding those who create problems for the administration of the Salafee Masjid by accusing of being Hizbi and in other ways.
An excerpt from the a khutbah by Br. Abul-'Abbaas Moosaa Richardson hafidhahullah encouraging the Muslims to be vigilant in supporting their local masjid, being active in helping, using one's wealth and supporting the spread of Islaam.
He also cautions the listeners against speaking out against the leadership of the masaajid, their financial affairs and questioning the worthiness of their positions. The evil and fitnah of these actions and how the Shaytaan intensifies in his efforts to separate the people as the community grows in size. The speaker cautions the listeners to record the statements of those who whisper doubts in to the community, to hold them accountable, to verify their claims and to admonish them for their rumour-mongering.
An important reminder for every community - to busy ourselves with good and to leave of useless banter and ill-speech.
