Moulana Abdur Rahman Sahib had related the following incident:
There lived in Ambala a person who was bay`at to a shaikh who lived in the mountains. This mureed used to be called Punjabi Mulla. He would pay his shaikh an annual visit. As he grew older, climbing the mountains became difficult for him. Once, whilst climbing the mountain he began thinking to himself that it would be much better if he received permission to derive benefit from the grave of a certain buzurg buried in Ambala. With these ideas still lingering in his mind he eventually reached his shaikh. Upon reaching, the peer sahib told him, “A certain buzurg is buried in your area. Go to his grave and derive benefit from him as climbing the mountain has become difficult.”

The mureed was overjoyed since he had received permission without even requesting. After returning home, he began frequenting the grave of this buzurg in Ambala who set his mind straight (in the following manner).  When he got up for tahajjud the buzurg in the grave said, “My son lives in a certain area and he does not have fodder for his horses. Provide them with fodder.”  Thus, he made the fodder available for them and returned. As he sat to make zikr, the buzurg instructed him clean the stables as they were filthy.

This mureed thought to himself that it would have been better to climb the mountains once a year. When he returned the buzurg reprimanded him from his grave, “You do not need to come to us. Return to the buzurg who you used to previously visit on the mountains.”

This is the effect of not acquiring tauheed-e-matlab. The saalik is unable to do anything and he thus remains deprived

Example of tauheed-e-matlab
Q: I have taken bay`at at your hands and I stay in Gangoh. I desire to do my islaah by Moulana Salman Sahib. I will follow whatever Hadhrat has to say.

A: Say for instance, a one and half-year-old child is seated in a group of women amongst whom is his mother, sister and aunt etc. The child will sit in the laps of each one of them, but when he is hungry, only the breast of the mother will open out to him. He will not go to anyone else because he is only satisfied through his mother.

Similarly, a patient knows that there are several doctors in his town. However, he will visit the doctor in whom he has confidence despite him knowing that there are other doctors who are better than his doctor and he will respect each one of them.
In the like manner, one should love and honour all the mashaayikh, but one’s training and reformation will be done at the hands of the buzurg to whom one has handed himself over. If one does anything to the contrary one will be in a state of worry and will not be successful in this path.

In relation to this there was a person who despite him having islaahi ta`alluq (spiritual relationship) with a particular buzurg, began following the ma`moolaat shown to him by another buzurg. There was no limit to his worry and confusion. Eventually, he went to Jalalabad by Hadhrat Moulana Maseehullah (ra). Hadhrat was very upset over what he had done and said, “Your situation is very difficult. Why did you have to go to a second buzurg after forming a relationship with the first?”
