Answered by Sayyidi Habib Umar bin Hafiz (may Allah protect him and benefit us by him)
If someone bestows abundant prayers upon the Prophet ﷺ it helps them to overcome obstacles on the spiritual path, remove blameworthy qualities and gain noble qualities. Then through the blessing of bestowing those prayers, Allah unites that person with a shaykh who will be a means for them to reach Allah. So bestowing abundant prayers upon the Prophet ﷺ (and also abundant istighfar) is one of the best means to prepare someone for spiritual progress and facilitate their meeting with their shaykh.
