Hazrat Moulana Muhammad Ilyaas (rahmatullahi ‘alaih) once mentioned the following:
Before performing salaah, one should mentally prepare oneself for salaah (by pondering over the importance and greatness of the ‘ibaadah one is about to commence). When a person does not mentally prepare himself for salaah, but instead rushes to commence the salaah, then he will perform the salaah in an unmindful manner. Hence, before commencing the salaah, one should ponder over the importance and greatness of the salaah one is about to perform.
It is for this reason (in order to mentally prepare oneself for salaah) that sharee‘ah has commanded that one first perform the sunnah muakkadah or sunnah ghair muakkadah salaah and call out the iqaamah, etc. before performing the fardh salaah, so that one may acquire the desired level of concentration in one’s fardh salaah.
However, it is very unfortunate that we do not understand the benefits of performing the sunnah muakkadah and ghair muakkadah salaah, calling out the iqaamah, etc. and nor do we derive the desired benefit from them. Hence, as a result, we perform our fardh salaah in a deficient manner (without any concentration and devotion).
اللهم إني أسئلك تمام الوضوء وتمام الصلاة وتمام رضوانك – آمين
O Allah! I ask you to bless me with the taufeeq to perform complete wudhu, complete salaah, and to acquire Your complete happiness and pleasure, aameen!
