Basically the knowledge that the Prophet (PBUH) can teach is far beyond what a person can acquire; it is a divine knowledge and it is present. Therefore, this knowledge not only shows us the truth but also bind our life with the divine world. It is mentioned in the holy Quran that, do not consider prayers and Salawaat for the Prophet (PBUH) the same as for any other person because with the divine power, the Prophet (PBUH) can bring a person out of the darkness into the light as mentioned in Ayah 43 of Surah Al-Ahzab; he can be a cause of bringing a person nearer to God, as mentioned in Ayah 99 of Surah Al-Tawbah; he can purify any uncleanness from the soul as mentioned in Ayah 103 of Surah Al-Tawbah and similar cases.
