Performing Salah alone in a Saff

When one is performing Salah in Jamaat, it is not good to perform Salah alone in a Saff. When a person comes to the Masjid and finds that the Saff are filled, then he must not stand alone. It is recommended to draw a Musalli behind in order not to be alone in a Saff. This is the principle. By applying this principle, it is possible that the person does not understand and breaks his Salah. In such a case, one should not draw anyone. It is better to perform Salah alone than breaking the Salah of a person. Nowadays, good people also do not know the principle. That is why this principle must not be applied because a principle is applied to set things right. If due to the ignorance of people, it becomes a means to cause disruption instead of setting things right, then it is of no use. One must refrain from it. However, one must continue to educate people in order for them to reach a stage whereby all principles can be applied.
