Instructions of Muslih al-Umma Shaykh Wasiullah (Allah have mercy on him) in particular to his associates and admirers and in general to all Muslims.
I have received information from various places and reliable sources that in some localities people are meddling with the Tablighi jamat. They neither perform a work of deen themselves nor they allow others to do so by creating many obstacles in their task. I consider it to be a extremely bad thing that an individual neither does a work himself nor he allows others to do so and in addition he makes so many objections on them that they are troubled and abandon the task itself.
The need of religious effort in this era is quite evident. It is vividly obvious that many people are required to do this task. It is well known that in every era there will be some servants of Allah who will serve the religion ardently and safeguard it with their soul and life. It is possible that there may be various different ways to fulfill this single purpose. Hence, in this era the truthful scholars (may Allah reward their effort) are doing this struggle to the best of their abilities.
Even if someone disagrees with a particular methodology the best thing to do is to continue working according to his own method to the best of his ability. However, he must also encourage, help and supplicate for the others working for the religion. If he comes to know about some of their lapses then wishing them well he should advise them politely. He should neither abuse the Jamat itself nor blame their elders due to the slips of few individuals or lay people. I detest this extremely and consider it to be a source of fragmentation among Muslims. This is not the time for such things. It is essential to make effort to create mutual love and friendship among Muslims and get rid of envy and enmity form their hearts. Mutual co-operation and unity are the stepping stone for any effective religious or secular endeavor.
It is for these reasons I instruct in general to all Muslims in particular to my associates and admirers that the should not meddle with any group that is doing religious work (including the Tablighi jamat and others). Instead they should help and assist them. If they can not do so then they should at least supplicate for (Divine) good for them. This is because respected Mawlana Mohammad Ilyas (Allah have mercy on him) is from our elders. God-forbid, he is not an innovator or insincere individual, that his group be rejected and criticized.
As far as the issue of mistakes in the method of the newer generation is concerned it has come to my knowledge that the scholars and superiors of Jamat are aware of these. They are not negligent about these and will make effort on their own to make reformations. It should be none of of our concern to meddle with the effort of deen already taking place and unnecessarily open a new gate of calamity (fitnah) among Muslims.
In these perilous times I consider most minute of the calamities (fitnah) to be fatal for Muslims. Therefore, I want to remain aloof from them and recommend my admires to do so. This is because the religion is to offer (beneficial) recommendation.
